Russell's first commercial success as a songwriter came when Joe Cocker recorded the song "Delta Lady" for his 1969 album, Joe Cocker! The album, co-produced and arranged by Russell, reached number 11 on the Billboard 200. Russell went on to organize and perform in (playing either piano or lead guitar) the 1970 Mad Dogs & Englishmen tour, using many of the musicians from Delaney and Bonnie's band. "Superstar", co-written by Russell, was sung by The Carpenters and other performers.
