You're not the only person I've heard say that, which is why I said what I said about wanting to hear Dave's side of that conversation. Something doesn't add up there. Yeah, Dave can be as grandiose as it gets, but he was making statements about it being a tribute show. He clearly knew it was a tribute show. So, even with Dave being Dave, it doesn't make sense that he'd shoot down a segment about Ed. Something tells me Al wanted to something bigger than just, for example, what Pantera is currently doing with Cemetary Gates for the brothers, and Dave basically told him something to the effect of, "that's too big, it'll wreck the momentum of the show, etc. etc."
What I don't get, was that if Alex hated Sammy that much, how in the FUCK was everyone going to coexist on that "Kitchen Sink" tour that was planned before Ed's cancer came back? The book came out in 2012 and Sammy did the Cabo Wabo deal in 2007, so those bridges were burned LONG before 2019.
