Dick Van Dyke Sings Lost Lyrics To Theme Song | Two Versions | The 2003 TV Land Awards Show

This happened during the First Annual TV Land Awards which aired on March 12, 2003 on TV Land.
Dick was part of the award show opening musical extravaganza in which he sang the theme song to the Dick Van Dyke show in 4-part harmony, and then he sang it again later (a cappella) at the insistence of Carl Reiner. I included both here, but started with the a cappella version because I think it's the most special.
From my VHS collection recorded via Comcast Cable in Eugene, Oregon.
