I'm emcee for a folk night coming up. Got me thinking; what would you consider the do's and don't of a good emcee? Any horror stories? What separates the goouns from the baduns?

My worst experience was some guy who asked to mc one of our showcase nights as a way of getting into the local mc 'BIZ'. I actually heard him say he refused to interview performers prior to their introduction. He then proceeded to tell the worst jokes and berated the audience when they didn't laugh. So he's become my benchmark of total suckage in the mc department.

Any ideas? SB
