Oh wow! I nearly said Michael Jackson earlier, partly in jest, partly in... oh alright... jest... :lol: (he was the most famous musician I could think of, but I couldn't imagine how you'd be playing in front of him).
But yeah, he definitely counted as a musician in my books. Not one of my favourites, but pretty bluddy famous all the same (not even counting the later "infamous" non-musical stuff) - yep, quite something to have played in front of him :D
