There's a funny video on Youtube of comedian Bill Burr talking about the time John Lennon got to play with his idol Chuck Berry on TV and he analyzes the video to show the moment during the song "Memphis Tennessee" when Chuck Berry first hears Yoko begin to scream for no reason. The look on his face is hilarious. The video is very crude, lots of profanity because that's Burr's shtick. But if you can live with that, it's a funny clip.
