I ran into Phil Jupitus in Selfridges a few years ago, the morning after watching him perform in 'Hairspray'. I blurted out something like 'wow hi you were so good last night derp derp hi' and he pulled a silly face at me and I scurried away... it was all very mature. I think he was with his wife. He looked much larger in person, although that was when he was bigger in general.
Oh and Geldof lives in my hometown, I'd see him occasionally in the crappy public library, which was surreal. May have been a homeless guy though on a couple of occasions, we still liked to think it was Bob.
Annd my ex's dad used to play with Ozzy Osbourne, if that counts. ;D
