And I agree re Rick Wright - I didn't see him at all during Breath, I was worried he wasn't even onstage!
I'm off to see it again (BBC1 in the UK had the entire performance uncut) my first impression was the same as the other guy on here - Gilmour wasn't too forward in sharing Waters enthusiam -- so I won't be saving up for a reunion tour ticket just yet

Even though Gilmour was on SUPERB form!
