This was on BBC Four last night.

I can wholeheartedly recommend it. They show the very first TV appearance by the band that would become sky (with Harold Fisher on drums) and there's an interesting comment by John Williams re. Kevin Peek/The Shadows (which seems to confirm something I had heard a couple of times before).
Enjoy!
