Daryl Davis told us how Chuck Berry appeared from behind the curtain at the start of his New Year's Eve show at B. B. King's. Here he is, doing it. How many times do we get to see Chuck Berry play these days? Not that often. And it's another good chance to see and hear Davis, too. He's got a bit of that Johnnie Johnson magic, filling seamlessly between Chuck Berry's licks. Thanks Peter, and Doug.
