I saw him at a G3 concert at The Hard Rock Hotel in Vegas. We got backstage passes so there was personal time with the musicians. I bought a T-shirt and I also brought a sharpie with me cuz I knew we would meet him. I asked him to sign my Tee and he said sharpies don't work well on T-shirts. I told him to give it his best shot. He seemed annoyed but did it. It worked.

G3 at that time was Satriani, Vai and Malmsteen.
