That's one of the first things people say after they've seen Bruce for the first time "How does he do it?"

The difference between him and Jon (and anyone else) is that he goes out with the a single minded approach to playing live, which is to give 100% and play until he's given his all. The man never has an off night and physically and vocally pushes himself EVERY SINGLE SHOW. The likes of Jon give their all on the rare occasion they can be bothered and probably couldn't do it every night if they tried. No one expects a 63 year old man to be running around and jumping into the crowd for three hours but he does it anyway. He's the hardest working front man I've ever witnessed.

Bruce is a wonder and you have to see it to believe it.
