Well I won't join anybody on stage until I've had three beers and don't give a damn about whether I know the music or not, but I'll sit in the middle of the audience and play percussion on my cup and spoons, sing along with all the songs I don't know and try and fail to sing harmony, then I'll shout out jokes about the Mudcat so that those on stage can answer back and the rest of the audience will wonder what the hell is going on, and yell at anybody who tries to talk while you're performing to "Shut UP! and be a little sensitive for Christssakes!"...
