 Phil Upchurch on rhythm guitar. Just crazy cool stuff, man. Maurice White from that started Earth, Wind & Fire. Boom, he's playing drums on a lot of this stuff. Unbelievable. Chuck Berry with the killer lyric of all time. Again, he gets so much notoriety around his playing around the groove. You can't deny it. He had one of the most unique styles ever. Nothing sounds like Chuck Berry, but Chuck Berry. A lot of people emulate it, but that groove there, he came up with it.
