Since you care, I'll keep you informed if I learn anything.

That particular special has been shown on Public Television on a couple of occasions and of course, I purchased the video. It's a great concert that was done in either '81 or '82 in the Dominican Republic. It's possible that PTV has the rights to it because it is almost impossible to find it anywhere with the possible exception of E-Bay. I made a donation of $75 to PTV to get my copy.
