On January 25, 2003, Rock and Roll Hall of Famer Johnnie Johnson -- the man Rolling Stone called “the greatest sideman in rock and roll” for his groundbreaking piano work with Chuck Berry -- stepped on stage at Houston, Texas’ Reliant Stadium. He joined his hosts, The Rolling Stones, for a rousing rendition of Honky Tonk Women. After hanging out all night with Keith Richards, Johnson got on a plane and flew to Kentucky. There he reunited with his good friends, Grammy-winning Southern blues-rockers The Kentucky Headhunters -- brothers Richard and Fred Young, Greg Martin, Doug Phelps and Anthony Kenney. The plan was to have Johnnie lay down some piano for the band’s upcoming release, Soul. But the vibe was too strong and the music too good, so the tape just kept rolling.
