It's the rebroadcast of a 1970 TV show called "London Rock" and it contains wonderful footage of the Faces, Fairport Convention, Marc Bolan/T Rex, etc in their prime. It would be awesome if someone could record it (or, even better, do a stream capture) and torrent it as a DVD.
It is broadcasted on Sky Arts 1 on October 7 & 8, for further info:
Here's a YouTube clip
