There was very little of that kind of nonsense at my show. I mean, it was a metal show, to be sure, and it was an energetic crowd, shall we say, but not that kind of dickishness.
I'm a Bruce fanboy and apologist, but I have to say... if it WASN'T that egregious, he's basically the PhD of metal, and so is smart enough and cogent enough to make that clear in his speech. "Hey, you fuckers; I don't know what happened down here, but there's no call for beating up punters, and there's no call for punters to be assholes. We're here to have fun, and we're here leave the outside outside for a couple hours!" Or something like that (I'm thinking of something like his speech before "Blood Brothers" on the last tour). The only thing I can say is if the kid was backstage, maybe Bruce saw his wounds and was moved by that.
