I must be dead. This must be heaven. Bedazzled just posted this literally a few minutes ago. Holy jesus...This is actually just as much, if nor more, Memphis/Stax stuff than Muscle Shoals, but who cares? This footage is priceless! And yes, Spike, that looks like Isaac Hayes on sax to me.
Thanks to Modculture for posting this...it's not often we get to see our favorites from the sixties in color. This apparently dates from 1968 on French televison. Groovy!
