Awesome! Nice piece to have signed.
I've been to about 20 shows, most recently in April. I tried to get his autograph many times, but never came close. Then, in 2009, I was working in the stadium during the Super Bowl week. I got to see his rehearsal, and as I was leaving I heard a familiar voice. I looked over my shoulder and there he was walking behind me. I stopped dead, probably with my mouth open.
He came up and said "How you doin'?"
I stammered something about how great the show (rehearsal) was, I was a huge fan, and how he changed my life.
He said "That's nice. That's nice. I'm a big fan of yours, too." and laughed. Then he slapped my back, shook my hand and said "Take care".
I never even thought to ask for an autograph.
