If you haven't been there, you won't know.

well that might be true, but I'm pretty sure this is totally about richard being "fired", shutting his mouth and playing on the wall tour, then after roger leaves, they are in their own band. Gilmour's part might either be talking about richard, as it says hes paler, hes fading, but he can "have the words right from his mouth" in saying that gilmour is finally standing up and taking charge, and they go on to record a huge album, then this one ie.: "we can hear ourselves again". I mean read nick's book all of this seems to fit with...

No no no. It is true. If you haven't been there you won't know. (I've been there)

@afenton What do you mean "there"?
