Jeffrey, I saw Leon Russell live in 1972 at the Anaheim Convention Center. It was good.
This is the Long Beach and Charlotte shows. They did film at Anaheim too and I also have those original reels as well but could not get a workable signal off of them, sad to say.
We barely got useable signal off the Long Beach and Anaheim reels!
But yes, if you saw the giant TV cameras there, this is that recording.
