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.
I beg to differ with you there, bub. I think the Bashams are way better now that they're part of JBL's stable. I don't think the Shane Twins will be replacing anyone, rather just adding more to the mix.
