Which soul singer had a hit with “Mustang Sally” in 1966? The answer is Wilson Pickett.

“Mustang Sally” was written and first recorded by Mack Rice in 1965, when Rice’s version reached No. 15 on the U.S. R&B chart. Wilson Pickett’s 1966 recording transformed the song into a much larger hit and appeared on his Atlantic album The Wicked Pickett.

Pickett’s version peaked at No. 6 on the U.S. R&B chart and No. 23 on the pop chart. Its driving rhythm, gritty vocal, horn arrangement, and Muscle Shoals musicians helped establish it as one of Pickett’s signature performances. The backing lineup included members of the Muscle Shoals rhythm section and the Sweet Inspirations.

A common mix-up is Mack Rice, who wrote and originally recorded the song, rather than Pickett, whose better-known version is normally intended by this question. The song later gained another generation of listeners through The Commitments film and soundtrack in 1991.
