I just finished watching No Distance Left To Run and it left me feeling really good and also very sad I wasn't at their glasto gig a few years back. I reckon I might lie to my kids in the future and tell them I was there - I should have been really.

Anyway, what's your favourite music documentary? There's loads of alright ones, about flower power, or punk, or grunge or the British Beat Invasion or whatever (actually the beatles anthology is great). But which ones are actually brilliant?

I've heard about one with loads of 70s rock stars on a train together getting fucked up and playing music. What's that one?
