What is so impressive is that's its a live version and not a studio recording. The guy just walked on stage and sounded like that with 1965 microphone and amp.
This is Bobby Hatfields song, make no mistake about it, Angelina did a nice cover, Elvis poured his heart n soul into it but nobody sings this song like Mr. Hatfield.
It is talent with a lot of practice to be great. That is what auto tune robs singers of. They can't reach true greatness. They don't have to give it their all because a machine is doing it for them.
I really wish I could watch one video of a classic performance without seeing whiny comments from bitter old Boomers complaining about auto tune. Get a life, you sad geezers. You ruined the economy and the environment; nothing to be proud of.
Gotta be one of the most moving ballads ever voice of an angel. Never gets old and amazes those who hear it for the first time. pure talent cant touch this
This is a "Live" performance done back 55 years ago in 1965. Composer's Alex North's (1910-1991) "Unchained Melody" never sounded so good then when the late great Bobby Hatfield (1940-2003) of the "Righteous Brothers" sung this with the beautiful instrumental arrangement of the "Andy Williams Orchestra." The string section of the orchestra is to die for. This performance alone has solidify Bobby Hatfield as one of music's greatest "Tenors" of all times. Rest in peace Bobby Hatfield. For you left us a great legacy of songs generations will come to enjoy and marvel...
I was 16 when this song came out. Didn t realize then how talented he was how perfect that love song was and that I now can listen to it over and over. And so appreciate seeing young people praise and recognize the most talented singer
This man had talent no gimmicks to his voice pure magic. many a GI loved this song while in Vietnam I thought of my love back home and made it back, RIP my fallen brothers who did not return. My love and I just celebrated of 50th Anniversary still love this song.
Beautiful reaction to Bobby Hatfield pouring his soul into every note in Unchained Melody, and melting all our hearts! Incomparable vocals- The voice of an angel RIP 💖 🕊 ⭐
The first high note was Perfection. Wait for it. How would you like to slow dance with a tender man like this? I was a teen in the 60's we need to bring back the sock hops.
That’s the emotive power of the legendary BOBBY HATFIELD (RIP 1940 - 2003) - arguably the greatest tenor singer EVER - his pronouncing and clarity is perfect. This was his 1965 masterpiece 👌
This was before Electronics could adjust your voice to sound how they need you to. This was REAL RAW Talent, I remember when this version came out my sisters would just keep repeat playing it for hours. Back when men would sing with emotion to women not speak a phrase at them. But it never gets old, Thanks for the memory's.
The only one who captured our hearts until todate to sing this song. it was too perfect that your soul is being brought to heaven! oh wow an angelic voice really!
The righteous Brothers always did solo songs on their albums and this one turned into a single that reach number one. A little history they both wanted to sing it and they flipped a coin Bobby hat field won. When Bobby recorded it Bill medley said he was glad he lost his coin flip
You nailed it !! Bobby Hatfield is mesmerizing when he performs. You would be surprised at the many facets to his great talent--he sings all kinds of songs, including more beautiful love songs. rockers, Doo Wop, and wonderful inspirational ones. You will be hooked. Loved your reaction. Cathy
Thanks Ovuada - this is Bobby Hatfield solo -- LIVE - I heard that he was nervous b/c his MOM was in the audience -- I'm sure she was proud! (there are other songs with the two in harmony - which are awesome.. although they are not actual "brothers") - what I really love about Bobby's performance here is that it seems to effortless - he does not strain or scream any of his notes -- just sings them straight out...
Andy Williams show, live orchestra, live performance, I'm so glad they taped this, Bobby's performance is perfection, I cannot stop listening to this version rather than the recording released. It's powerful without power singing. Josh Groban is probably looking for a new job after hearing this lol.
I’m reminded by a famous radio personality who used the phrase, “Talent on loan from God!”…and y’all just heard it. Amazing rendition and made personal by Bobby as distinguished from the outstanding Studio cut.
Thank you for your great reaction to this beautiful song. Others tried, but no one could sing this song like the great Bobby Hatfield!! I hope to listen to more of your reactions, as this was my first time watching you!
This guy can sing a song make no mistake about it! There's been some truly great Soul Songs over a couple of decades but Bobby Hatfields rendition of this great song Unchained Melody leaves the best of the best in its wake! What a song! What a singer! Melb Australia
Saw this performance when it first aired when I was 10 years old. Been watching it ever since and still wondering when Bobby Hatfield has a chance to breathe while he sings this masterpiece!!!
I'm 74 and I can remember dancing with that special girl to this song at our high school dances. This is why music such as this has lasted over 66-70 years.
The way he (we) vantrickulated every fiber of his being through his voice indelling sound waves the very essence of his true feelings of emotion capitalizing on his unfading love with tenderness gives effortless power of electricity which energizes a person to want more and to share in giving the whole world the same endless journey everyone needs to endure Love in TIME,,,, Forever
I dream of dancing with the woman I love to this wonderful song .. soon afterwards a bit stunned but her accepting my proposal to marry me .. aaahhh .. tears of joy ( and relief ) .. lol 🙏.. beautiful ❤️ reaction to this classic` m'lady ~ 😘
Back in the day there were many "Crooners." Bing Crosby, Frank Sinatra, Perry Como, Dean Martin, etc. They used singing to get to the hearts of women through romantic swooning. You were very receptive to swoon & this number is one of the most powerful. Many others too, Frankie Avalon, Andy Williams who hosted this show & Bobby's parents were in the audience.
Bobby Hatfield dedicated this song to be a singing love letter from us guys over in VIETNAM at this time {1960s} to our wives and girlfriends back home , while there in country , we very rarely got a chance to just sit and write letters home , with trying to duck Bullets and incoming Mortar rounds , so I would occasionally just jot off a few lines that simply said "HONEY, IM OK, PLEASE LISTEN TO BOBBY , HE'S GONNA TELL YOU IN A SONG HOW I AM FEELING ABOUT YOU RIGHT NOW , GIVE THE BABY A KISS FOR ME , WAIT FOR ME , I'LL BE COMING HOME WAIT FOR ME ,I LOVE YOU BILLY
I know about this. When they had to deploy, the hippy fucks started playing "love the one you're with." Trying to get young women to cheat on the guys in the mix. Love generation........riiiiiiight.
*The combination of his VOICE QUALITY, RANGE, CONTROL, VERSATILITY, EASE OF DELIVERY--->this is by far the BEST VERSION!!! Also he did not put on a SHOW by dancing or gyrating, allowing you to concentrate on the song. FINALLY, this performance was done in 1965, where there was no electronic apparatus to 'enhance' the voice. A singer in that era had to have 200% talent--->WHICH HE DEFINITELY HAD.*
I have to say. I am 83 years old and it makes me so happy to see you young people looking back to my youth and realizing that our music was great then and even better today. Thank you. My thoughts. If you wonder why boomers hate AUTO TUNE so much, this is why. We miss the days when singers could actually sing! No tricks, no redos, no second chances, no auto tune, no nothing but his talent.
Thank you so much for your reaction to this beautiful song done by Bobby Hatfield. I grew up in this time and actually went to the same college as they did in Santa Ana, CA. Bobby's range and vocal ability are second to none. This song was very carefully crafted. There were many very romantic songs back in the day. The Righteous Brothers rendition of Unchained Melody has a special place in music history. It has been chosen as the #1 song in the twentieth century above all others. Over time, there were several renditions of this song by other artists before Bobby to it to a new level. Your reaction to this music was very natural and you are lucky to be so sensitive. There are very, very few songs that can make the listener reach a new level of emotional feeling and many people actually get goosebumps listening to it. Many cry from joy. While more modern songs out there today have merit, I am hoping that you will listen to this special song many more times in your life. Doing that will give you love, hope, peace, and joy. Thank you again for making your wonderful video! Best Wishes! Michael USA
Luv your reaction - for sure it's 'normal ' cos this is the best 'Love Song ' ever - I know cos I've sung it to all 3 wives.. it still works for number three
I have actually listened to it and done a reaction to You Have lost that loving feeling, it was so beautiful 😍 Here is the link to the video th-cam.com/video/VlvApcYUIQk/w-d-xo.html
The love songs of today is like a smashed Rock covered in mud with bird poop on it when compared with the love songs of back then which is like the most beautiful bouquet of flowers you ever saw.
And Bobby Hatfield had such a great vocal range in him,it was fantastic when combined with Bill Melody's lower vocal tones. If have ever seen the movie "Dirty Dancing" then you have Bill's voice in the song I've Had The Time Of My Life in which he sang in.
Beautiful singing, beautiful song and no electronic just skilful emotional genuine live performance. By the way you are beautiful too. Loved seeing your reactions 👍🌹
watching you melt to the music I grew up with was amazing my sisters use to play this all the time if you get a chance listen to Otis Redding ( Dock Of The Bay ) If you would like any more suggestions give a reply
OVUADA HE GOT YOU SWEETIE PIE WOWWW YOU PROBABLY NEVER HEARD SINGER LIKE THIS CALIBER BEFORE LIKE BOBBY HATFIELD HE MELT YOU GOOD SWEETIE PIE BY BABY LOVE YOU
You may want to listen and react to the following Righteous Brothers songs: 1) Ebb Tide 2) You've Lost That Loving Feeling And a song by the group Heart named The Dog and the Butterfly. Best Wishes! Michael
The Righteous Brothers and a thousand others were just the wallpaper of my youth. When your living inside a bubble of perfection... it just seemed normal.
Bobby Hatfield crushing another heart after 50 plus years.
never a truer word said, beautiful isn't it?
😄😄😄 well put.
Classic
How many women has Bobby Hatfield made them fall in love with him or others.
What is so impressive is that's its a live version and not a studio recording. The guy just walked on stage and sounded like that with 1965 microphone and amp.
This is Bobby Hatfields song, make no mistake about it, Angelina did a nice cover, Elvis poured his heart n soul into it but nobody sings this song like Mr. Hatfield.
I totally agree with you
TF is Angelina?
@@brittanygarrison8030 Just type "Angelina unchained melody" in the search field above.
When you hear it done perfectly everything else will be second best
@@kkkmaniak always
A master course in how to sing. Bobby didn't need no auto tune. A gift from GOD
It is talent with a lot of practice to be great. That is what auto tune robs singers of. They can't reach true greatness. They don't have to give it their all because a machine is doing it for them.

@@madgepins1967 lol you don’t know me so I’ll be nice. Go suck Hillary’s dick and have a nice life.
I'm 64 and i can say i grew up in the best music era ever .
Agreed! 👍
I'm 71 , AND DEFINITELY grew up in the greatest era....EVER!
I'm 66 and I agree. The music was awesome in our times.
Yeah, I'm 69 and asking what happened? No one is singing like this today.
Me too.Just wish I could go back and do it all again.
Bobby hit 20 different notes (almost 2 full octaves) perfectly. NO AUTO_TUNE, just pure talent!
24 at last count
Bobby had a 6 octave range up to counter-tenor. On the soundboards, we call that 'Talent'!
What would this world be like if more woman were still sang songs of love like this, instead of what they hear today?
What the hell is your point?
Dude was velvet and satin mixed together! Perfect! RIP Bobby and TY for your life!
Richly smooth, even on the upper end. Just so pleasant.
His voice is like velvet, and it wraps around your entire being. He is / was amazing!!!!
Gotta be one of the most moving ballads ever voice of an angel. Never gets old and amazes those who hear it for the first time. pure talent cant touch this

Yasss he left a great legacy behind 🙌🏽
My heart breaks when I think of how he died. I don't think Bobby had any idea how
much he was loved ❤
Bobby humbled everyone with this performance! Peace!
This is the most beautiful love song ever ❤.
You can say that again 😘
And Lay, lady, lay.
@@ovuadaokpen Yeah!
I was 16 when this song came out. Didn t realize then how talented he was how perfect that love song was and that I now can listen to it over and over. And so appreciate seeing young people praise and recognize the most talented singer
It's a shame this version wasn't used for the 45 rpm record. It basically had been gone unknown to many. Well, until TH-cam.
He was so handsome and pure raw talent. His voice was awesome! RIP Bobby❤
THE GREATEST LIVE SOLO PERFORMANCE BY THE LATE GREAT BOBBY HATFIELD! NO ONE COULD EVER SING IT BETTER! 22 NOTE CHANGES! INCREDIBLE! RIP BOBBY!!
This man had talent no gimmicks to his voice pure magic. many a GI loved this song while in Vietnam I thought of my love back home and made it back, RIP my fallen brothers who did not return. My love and I just celebrated of 50th Anniversary still love this song.
I like how he bites his lip at the end as he thinks,yes,I've nailed that!!
he was super nervous because his parents were in the audience and I think the lip bite was like a bit of relief and "yes I nailed it"
The one song and performance that will always remain new
Talent like this cannot and it will not be replicated. No earplugs, electronics, or any other crap.
Beautiful reaction to Bobby Hatfield pouring his soul into every note in Unchained Melody, and melting all our hearts! Incomparable vocals- The voice of an angel RIP 💖 🕊 ⭐
I definitely enjoyed every bit of this song
We would definitely miss him, but his songs live on
@@ovuadaokpen 💜
I danced to this with my wife while we were in high school. Helped us fall in love.
Wow that’s truly beautiful and romantic
Me to... time goes by.....
Excellent reaction! I think you get how good this performance was. Bobby Hatfield was really the goods.
One of the best artists of the golden 60s! Pure talent.
The first high note was Perfection. Wait for it. How would you like to slow dance with a tender man like this? I was a teen in the 60's we need to bring back the sock hops.
He is just beyond perfect
One of the great vocal performances of all time
Why would anyone give this flawless and fabulous LIVE performance a thumbs down??? 🤦🏽♀️🤦🏽♀️🤦🏽♀️
You witnessed the best song and performance of all time. Your reaction was right on target. I subscribed right away. Be safe and take care.
That’s the emotive power of the legendary BOBBY HATFIELD (RIP 1940 - 2003) - arguably the greatest tenor singer EVER - his pronouncing and clarity is perfect. This was his 1965 masterpiece 👌
It can Not be done better.
Q.E.P.D ♥
Wow, wow is soooooo true. No one has sung this song like Bobby Hatfield. He owns it.
This was before Electronics could adjust your voice to sound how they need you to. This was REAL RAW Talent, I remember when this version came out my sisters would just
keep repeat playing it for hours. Back when men would sing with emotion to women not speak a phrase at them. But it never gets old, Thanks for the memory's.
This song is why I'm proud to be called Bobby!
Bobby Hatfield...making women swoon since 1962.
Not just women!
What makes this really is it's a live performance recorded in a hall not a studio. Eat your heart out modern "artists".
The Andy William Show - 1964.
Agreed! 👍
The only one who captured our hearts until todate to sing this song. it was too perfect that your soul is being brought to heaven! oh wow an angelic voice really!
