One of my fave celeb encounters was at a hotel in Shepherd's Bush, London. At that time not a great area but for recording studios. I'm with a friend who may or may not have been George Clinton. "HI!" In New York accent. I think "fam or old friend". Turn to say hi Cyndi Lauper!

Was working in a computer store, and noticed a man unobtrusively browsing at the back of the store. He was wearing crazy red pants, a black T-shirt, and a red ball cap. I approached him and asked if I could be of assistance. He looked up and smiled. Robin Williams.
