I came to this week's late, so the first one I read was aristo's @22 - I thought it wasn't worth entering! I'm surprised it didn't get a mention, though wil's (which I hadn't seen) was a great clue.
Thanks jono, and for the clips. The second one was interesting, if a bit worrying, and there was some classy Pink Floyd on the third one...
[I've had to have three goes at posting, as the Captcha box didn't appear on the first two. Anyone else had this problem?]
