Today, the highly intoxicated singer of my band decided it would be a wonderful idea to squat down and take a shit on stage in the middle of a gig. FML
I've been in a couple of bands. Experienced some rather questionable behavior, but never anything that extreme. I'd say have the band take a week or two off and find yourself a new singer. Maybe even disband and reform under a new name.
I don't think you'll ever get out from under the stigma of "singer ***** on stage." People just don't forget that kind of thing.
Nothing says "ROCK & ROLL" like a big steamy pile of number two!!!
"Middle of the gig?" I think that's the end of the gig . . . and the career.
