This is the best live version I've heard of
I Can't Turn You Loose by Otis Redding, with the Bar-Kays at a Chitlin' Circuit nightclub in Birmingham, Alabama, 1967. It's from a bootleg named
A Soupcan of Soul, Big Fro Discs (BF-007). Bassist James Alexander, eighteen years old at the time, was not in the plane that crashed into Lake Monona in Wisconsin on December 10, 1967, killing Redding and four members of the band.

DON'T try to play it online. I kept being redirected to some song from Southeast Asia.
