It looks like you have to register to download the torrent, and I've already got several Pink Floyd documentaries on DVD, so I doubt there will be anything new there to make it worthwhile, but thanks anyway, Gill.
I didn't get into PF till quite late, and the early 'spacy' stuff did nothing for me, but Dark Side of the Moon, and Wish You Were Here are both stunning works, which everyone who likes good music should have in their collection.
