Jazz guitarist John Scofield recorded a version for his album That's What I Say: John Scofield Plays the Music of Ray Charles in 2005, featuring blues guitarist John Mayer on additional guitar and vocals. Mayer covered the song again with his band during his tour in summer 2007. A version recorded live during a Los Angeles show during that tour is available on Mayer's CD/DVD release Where the Light Is. A Ray Charles tribute album also provided the impetus for jazz singer Roseanna Vitro's version – specifically, her 1997 CD, Catchin’ Some Rays: The Music of Ray Charles
