My earliest live show memory is from around 1980-81-ish. Lars Anderson's World League Wrestling promotion began airing on Duluth TV which we got as our ABC/NBC/CBS affiliates. They began to run the local arena a month or so after getting on TV. If I'd have watched it as an adult I probably wouldn't have liked it so much, but as a twelve year old (or so) I was mesmerized...Lars Anderson defending against "The Bounty Hunter", complte with a false title change and blood. Also a Tommy Rich knockoff ("Timmy Rich", if you can believe it) wrestling another lighter weight guy whose name escapes me (I think he was a Duggan...weird, I know), and JR Hogg and Cousin Jed, a hillbilly face team. Good stuff there.
The run International Wrestling out of Montreal had here was phenomenal. That was 1986-87. Bigger names including Gino Brito & Tony parisi, Dan Kroffat and Alofa, Abdullah the Butcher, Hercules Ayala, and Steve Strong, plus the debut of "Billy Fury", aka Vampiro, on their second show.
I think they were actually pretty stunned they did as well as they did...the first two or three shows were sold out (over 6,000 capacity), and they were still drawing 2500 - 3000 when the promotion folded.
Probably my favourite show was a summer 1985 Duluth, MN house show that had a great Ray Stevens/Nick Bockwinkel vs. Greg Gagne/Sgt. Slaughter match, with Larry Hennig vs. Michael hayes and Buck Zumhofe vs. Boris Zurkov on the undercard.
