It seems like the entire British invasion had harp players - The Yardbirds, Them, the Beatles, the Who, and a couple of other groups around Mayall and Canned Heat; sorry I can't remember, but I inhaled.
Rob Paparozzi was right about Huey Lewis and that Majic Dick should not be mentioned in the above harp dabblers group, he is a real harp player! as is Norton Buffalo.
But I do not recall hearing Jagger blow harp on the early stuff, just much later ala Aerosmith. When Sugar Blue studied with me, he had just played on a Stones tune and Randy Hennes had just done a Blondie cut because I remember that they talked about it at the lessons.
When did Jagger start?
