This happened in an outskirt of Flagstaff called Tuba City on an Indian
reservation.
What I heard is that before the show they agreed to let that guy's band
play AFTER Danzig because Danzig wouldn't go on later and change their
set time. However, right after Danzig played they started breaking down
the stage. So this guy's band expected to play and then that happened.
He was explaining that to Glenn and then the altercation started.
Maybe Glenn needs to re-hire Jesse James from West Coast Choppers for security again.
