Not sure if it's well-hidden on Youtube, was taken down, or if I just suck at searching.
There were a couple clips of what I'm told was a late 80's Great American Bash. Ron Garvin had taken a camcorder backstage and got some great candid footage of the Road Warriors, Dusty, Sting, Cornette, etc.
$30 for front row, 15 for general admission. And for those who follow these things, London and Styles was a fantastic match with a lame finish (German suplex double pin). Corino wasn't there, so Michael Shane subbed.
