I met Mick, at an 'after concert party' for the 'Doors', in 1968, under the Hollywood Bowl, in the basement. Actually, offstage, he is rather subdued, and polite..rather small and thin, almost sickly in appearance, but energy coming off him.
During the mid to late 70's, he used to do dialysis, to clean his blood from the drugs he was taking.
But one thing...he made it to 70!
