I don't know how many of you get to see Pamela Anderson's (Lee's?) show called VIP, but I believe Gilmour was on it. It is a rather bad show, but on this one episode Pamela was supposed to be protecting Paul McCartney. Now McCartney didn't actually make an appearance on the show, rather they used footage from a concert he apparently did in the Los Angeles/San Fransisco area.
On this footage there was a guitar player who looked like Gilmour and played like Gilmour. Now they didn't show Gilmour up close and I've only seen the episode once, and he wasn't listed in the credits, BUT I do know that Gilmour contributed on his last album.
Anyway if anybody knows more about this let me know. If it turns out that it was Gilmour I'd like to get a copy of this episode.
