Mitch Mitchell of the Jimi Hendrix Experience - Silver Sparkle.Don Brewer of Grand Funk Railroad (1969-1976 or later) - Red Sparkle.One more caveat about Charlie Watts... I read an article about him back in 1971 that he spent off-time from the Stones playing London strip clubs because jazz-style R&B was his favorite. Don't know how true that was, but there was a photo of him in the article playing on stage behind an exotic dancer. Most drummers of any substance play more than one style of music to expand their timing sense.

I hadn't heard the story about Charlie playing in strip clubs. But I know he plays jazz when he's not touring with the Stones -- I believe he put out an album as a bandleader in the early 90s.
