This is Biscuit from the comments section. This is a match from St. Louis in 1983 at the Checkerdome, Ric Flair defending the NWA title against King Kong Brody. The match is 2/3 falls and goes for an hour. Unfortunately the commentary is in Japanese, but it's really good video quality for the era and a great example of the main events we were fortunate enough to get here.
This would be Dave Meltzer's dream match. I believe he's raved about it before, in fact.
