Sad news. The Shadows went a little downhill after he and Tony Meehan left, IMO.
A bit of Zeppelin-related trivia: Tony Meehan and Jet Harris's 1963 single, Diamonds, is, according to many sources, the first No.1 single to feature Jimmy Page. Also, a young John Paul Paul Jones - then, John Baldwin - was a member of their backing group for a while.

That's right. And of course, Bill mentions in Rolling In With The Stones about how shocked he was that Jet wasn't plugged in on stage and someone - probably John Paul Jones, actually - played his parts behind the curtain.
Sad news. Great musician. I only saw him perform once; at a local working men's club in the 1970s. He was playing with his band the Diamonds, and played a selection of Shadows tunes and his hits with Meehan. Great player and a true gent, as I recall.
