I knew something was wrong with yesterday's clip. I thought Costello was the short one.
I was actually hoping to find the Harry Shearer bit about the concert featuring (I believe) the Who, the Guess Who, Yes, and the Band.
All right, no fooling, I really mean it, this time for sure. From the film "The Gay Nineties" (hey, this bit probably is that old), Abbott and Costello's pick for the definitive performance of "Who's on First".
