Well, the idea that years later people would be collecting video of these shows and watching all these different house shows was insanity back then. The absolute last thing on the wrestlers and Vince's minds. Think about it like this. When most bands go on tour, they'd have an exact setlist and rarely stray from it and how they played the songs, because the thinking was/ is that people payed to hear the hits. Bands like the Grateful Dead were extremely rare in that they changed every single show and played a different show each night. But they had an audience that expected that and wanted it. The wrestling fans going to WWF shows wanted the hits, so to speak. And Vince wanted a tight show that he could tour any city with.
