Quick story. Unbeknown to my friends, I was at this concert. My friends swore up and down that while watching the concert on tape when it first came out they all looked at each other and said they just heard me in the crowd. I bought the tape and listened and it's hard to tell your own voice so I just figured nobody can really tell for sure, bunch of drunks in the crowd, etc... A couple of years later, now married, the wife was watching the concert tape and called me into the room. She rewound the tape to the same spot that my friends had indicated and said, "listen...."
Hee, hee.... okay... so I was relatively close to the stage and I did have a few margaritas under my belt.
