Nope. No "Televised on the MSG Network - featured Vince McMahon on commentary" line before the result of the card on History of WWE, nor do I know of any of these matches being out there. The Hogan-Tito match you're thinking of is the rematch from 3/24/80. Untelevised cards weren't unusual back in the 70s and early 80s. Several MSG cards per year were untelevised for whatever reason. Too bad about this one, because the Bob-Ken match may have been good, and I believe this was also Tommy Rich's one and only appearance at MSG.
