Sorry to have to say this oldhippy, but i must be even older than you.
I saw Jimmy Vaughn (Stevie Ray's older brother) when he was playing in a local "combo" at age 17. Stevie Ray was still in junior high.
I saw Leonard Skynard way before the plane crash.
I have a tie from Carnaby Street given to me by Peter Noone of Herman's Hermits.
I met Robert Moog (Moog synthesizer fame) in 1968.
