I'm not 100 percent sure, but I think that may be my late friend, journalist Al Aronowitz, with his back to the camera.
I'm almost sure it's him. Al was a pretty burly guy in the early 70's. But, more importantly. he loved introducing artists to other artists, and he knew both Miles and Lennon very well at the time. Here he is with another Beatle. Speaking of Al and John...another link in the chain:
Hardly unexpected. Brooker was in Ringo's All Star Band the first time I saw Ringo (the all-British line-up with Frampton, Bruce, and Kirke).
T-Bone Burnett and Pete Townshend I know they toured together on the '82 farewell tour but I've never seen them together.
