I met him in Minneapolis...let's just say I asked him to sign an interesting spot on my shirt (without realizing it of course) and he was so sweet about it.
All you need to do is find out when they're near you and just go meet them!
Shit, I forgot to say about Bono! When I gave him the two drawings of him he said - ''Thanks so much'' like he REALLY meant it, in his beautiful Irish accent!!!!
