I once kissed (modestly) Syd Barrett. Not a sleeping-with story but has been known to cause a stir among my not-very-celeb-y friends.
Oh goodness, lucky you! He was so beautiful, so sad how he ended up.
I know someone who's had a tongue sandwich with one of The Smiths. Not Morrissey
It wasn't Johnny Marr was it?! If it was I'm ridiculously jealous. Boo!
I've been with a few folk from bands but only one person I'd say most people would have heard of. He's not a musician though and he's a bit of a tart so there's probably more than me that have 'known' him in this thread.
