My first accordion -- Batter Up!

I just started playing accordion. I picked a children's toy first off ebay but then started talking with the seller out of Philadelphia about what I was wanting to do. Liberty Bellows helped me out with a very inexpensive but VERY old Hohner from the 40s or 50s. It's old and shotty looking but they got it tuned and refurbed enough for my needs.
The song is Batter Up! from the Palmer-Hughes Accordion Course Book 1
