Garea and Martel weren't great cause of the benefit of hot crowds, comparison to today, or any other shit. If you watch them you'll see a great team and Garea was fucking great.
And Goulet doing that spot IS fucking great. Goulet was a great wrestler.
This idea that performing in front of hot 70's/ 80's crowds is some sort of non factor is nuts. "Well, sure, they had great matches and popped the crowds, but people liked anything back then so blah blah" is weak beer , bro. I've seen enough old footage to know that the crowds would often sit on their hands if the wrestling in the ring stunk.
