I know JD -- he's pretty insighful -- Muscle Shoals -- I think they overdubbed Wild Horses and some others there - they have that great group of musicians. They [Mick,Keef] wanted to do something there so they did. They also did Chess, of course -- but I'm not sure if I've seen Muscle Shoals.

ry Cooder first showed up on Let It Bleed -- and Keith got his tunings.
