Southern blue-eyed soul, the Box Tops' "Soul Deep". Recorded at Ardent Memphis, produced by the great bassist Tommy Cogbill and Chips Moman, also playing on this with the late session great Reggie Young on guitar, who's curiously panned hard-right in these days when the move from Mono to Stereo was still a work in progress. Cogbill was a great multi-instrumentalist (like Carol Kaye, easily at home on guitar or bass), and is on lots of Muscle Shoals, Memphis, and Nashville sides, where late in life he was a great mentor to the then-new-kid-in-town, the late Michael Rhodes. Cogbill is actually the bass on Booker T's "Green Onions" before they brought in Cropper's boyhood friend, the late Duck Dunn.
I grew up on stuff like this.
