Leon was first known mostly as a session musician, and played played with artists as varied as Jerry Lee Lewis, Phil Spector and The Rolling Stones. He had a solo career spanning the genres of rock, blues, and gospel. His first songwriting hit was for Joe Cocker's 1969 "Delta Lady", and Russell went on to organise Cocker's Mad Dogs and Englishmen tour. The man can beat a piano. He is on tour and I will be seeing him tonight (11-15-07) in Virginia Beach at a fitting venue for his style of music.
