Interesting. You know Brad Booth? I knew the guy back in HS days...some interesting stories. Some friends of mine are still tight with him. His poker career certainly went to shit. Still out there, though.
I've met a lot of musical celebs over the years; Seal, Chris Isaak, all the Nickelback dudes (ugh), AC/DC. Motley Crue, Carly Rae Jepsen, Korn, Deftones, FMN, Mr. Bungle, Joni Mitchell, Elvis Costello and Diana Krall (she was so beautiful in person, I legit was blushing like an idiot), a bunch more.
I work in the music industry, so the vast majority of these meets were in recording studios, through other music friends, etc.
My favorite was Diana Krall though. Meet her while on the ferry, after playing a weekend away. Elvis and their kids were there as well. I was sitting in my car, waiting to depart the boat, and they were walking by, looking for their car...she notice I had that "holy fuck, its you?" look. She waived, came up to my window, said "hello"...I mumbled something incredibly incoherent back, ugh. She then noticed my drums in the back of my car, she lit up, asking if I was gigging, etc. I told her the bar I played at, she got excited because she had played there in her earlier years as well. We talked shop for 5 minutes, while Costello stood there with the kids...she introduced me to him and the kids. Super nice people.
