Apparently two members of Wayne Hancock's band got into a serious fight in KC while on tour. The results were not pretty. (There's a link to a pretty graphic photo of one of the guy's injuries, so be warned.)
I once had a day job where as a manager I once had to deal with two guys in my shop who didn't get along; thank God it only came to words and raised voices, and not blows.
All I can say is: If you are a bandleader, may you never, ever have this happen on your tour.
