Some of the punk gigs I've seen, (old punk bands not all these w**ker yank new punk bands) the left and right wing used to kick off inside. I used to think its was funny watching all these idiots knocking 7 bells out of each other. Have drink, listen and watch the bands and fights. To me, it was the norm really.
As for the mosh stuff, I've never seen much of it at rock gigs. If it does happen, its not what I'd call a problem. But then again I used stand in the shelf at Spurs for years and I've seen a hell of a lot worse at football matches than gigs. Its all relative to what you perceive as unacceptable. People play up when they're drunk and excited, its just human nature.
Before all the porn shite hit the fan for that creep Gary Glitter, his gigs were had a mosh pit too! I went to two, for a bit of a laugh. I even got pilled up at one. :lol: shite gigs though. Most of it was mimed. That must have been around '92.
At BLS 5 years back in the Astoria, just when this forum got going, it was insane in there. It was entertaining though. Its all part of the experience for me. Nothing will change.
