Art Holliday was on my show this afternoon. When he’s not anchoring the morning news on KSDK-TV, Art is making a documentary about Johnnie Johnson, the Rock and Roll Hall of Famer who was one of the architects of that great American art form, best known for playing piano on those early Chuck Berry hits.

We talked about the rock legends Art has interviewed for the movie (from Eric Clapton to Bonnie Raitt to Bo Diddley to Bob Weir), why Berry hasn’t appeared on camera yet, how Keith Richards pushed for Johnnie to be inducted into the Rock Hall, and much more.

Listen to our conversation here.
