The show itself was broadcast on HBO and is otherwise notable for being Ric Flair's first match at MSG (which was on his first DVD). I don't know if it ever aired on WWE's pre-Network on-demand services, though.
Flair's first MSG match was actually on the 3/1/76 show, and that is the one on his first DVD. His second MSG match was indeed on the show headlined by Bruno vs Hansen, but that match, against Frankie Williams, has never surfaced that I'm aware.
Also, the botched bodyslam did make at least one other appearance on tape, on an episode of the old Tom Weaver Greatest Sports Legends show devoted to Bruno, in a blink and you miss it montage of Bruno's greatest foes
