I saw both of those last week. The Guitar Players at the BBC is a load of clips - U2, Jeff Beck, Dire Strais, Hendrix etc. Quite a good watch.
The Les Paul documentary is WELL worth the watch. I knew he played some jazz, and he had something to do with multi-tracking, but that was it. Turns out he was a superb player in his younger days, has a pretty big vintage guitar collection, invented multi-tracking and over-dubbing and has a wicked sense of humour ;)
Great program, well worth a watch :)
