This was recorded at Stax Recording Studios in Memphis with the Stax house band: Booker T. & the M.G's. Note the drum pattern: Al Jackson accents every third hit of his snare. This was David Porter's idea, although it wasn't easy for him to explain what he was looking for. Porter asked Jackson to play "the sound of horses," and he delivered the beat.
Steve Cropper added a dirty guitar sound, and Isaac Hayes played the clavinet (the instrument Stevie Wonder used on "Superstition
"). Background vocals were provided by another Stax group, Ollie & the Nightingales.
