Believe it or not, even with over 4,000 posts, I'm probably one of the few here who has never seen the Cavern show. I just never got around to buying it. Hopefully someday soon when I have some extra money. So, I can't comment on Gilmour's performance that night. But I do know one thing, there's no way David Gilmour sucks in general. No way. I think his work with Pink Floyd was superb. I also like his voice.
