I know it'll get moved into the O Club, but I figure more people would see it here. Ran across this looking for clips from shows I used to watch back in the day. Great parody of the old "Whos on First" gag. This is from the old kids series "Animaniacs", its supposed to be at woodstock.
Oddly enough its just a joke in the episode, the whole rest of the episode is all about the '60s and could have gone on without this scene (not like the whole episode was a setup for this one joke), but its a brilliant piece of writing and a great adaption of a classic, especially considering its from a kids show. Most kids would have no clue who these bands are.
