Fat Mike and the guy made up: http://www.jobsnhire.com/articles/13097/20141107/fat-mike-kicks-fa n-punk-musician-kicks-and-punches-australian-fan-on-stage-for-appr oaching-him-video.htm
That's pretty cool. I guess he got the kid beers and let him kick him as hard as he wanted backstage at the next show they invited him to. Both should've known better but that makes me think a lot higher of NOFX, even though I don't really give a shit about their music or Fat Wreck.
The opposite thing happened to my ex wife at a King Khan and the Shrines show. The keyboardist I think jumped into the crowd and getting back up on stage his boot slipped, nailing her right in the glasses (she was 5'3 with high heels so she always stood in the front) and broke them. Miraculously nothing else was broken. I wrote Vice Records, not to ask for any compensation or anything, and still got no response, not even an apology, which is all I wanted. I haven't listened to them since.
