1976 University of California outdoor show

[tdfwiner]

Does anyone know how much of the outdoor University of California show from 1976 exists? Or any of the other early outdoor/daytime shows for that matter. I just saw this clip for the first time a couple of days ago and it got me craving the whole concert again.

That show is obviously most famous for it's version of I'm so Afraid and there's also an awesome clip of World Turning floating around but I've never seen the whole show anywhere.

Someone really needs to light a fire under them so they'll actually clean up and release some pre-1987 dvds for us.
