This is Doctor John, sometimes known as Doctor John The Night Tripper. His real name is John Rebennack Jr. Dr. J is probably best associated with his biggest pop tune hit, 'In the Right Place at the Wrong Time' but beyond the psychedelic voodoo theatrics he used in the early seventies, John plays a blues form of New Orleans R&B. He is a noted sessions musician, playing piano on many album cuts with James Taylor, The Rolling Stones, Carlye Simon, Neil Diamond, Van Morrison, etc. etc. He still records and performs today
