This has been all over the internet in the last week and if you missed it

http://www.azpunk.com/ has a bunch of mirrors to the video.

Danzig screwed over a bunch of bands that were supposed to play and couldn't because he *had* to play at 10pm which fucked everyone up. And this fat guy from one of the bands confronts Danzig about it. Danzig flips out for no reason and pushes the fat guy and the fat guy nails him with one sweet shot.

:D
