I saw him once at Olympic Stadium in Montreal in the bad old days of the Expos. 5000 people in Olympic Stadium essentially disappear. The worst part, though, was the ride home. It was the night Elvis died and this 13YO (along with everyone else in the van) had no choice but to listen to Elvis tunes all the way home.
