Hi folks, I want to pose this question here amongst the seasoned gig veterans; hope this is the right place for it. I run a weekly blues jam session in a small bar. It's supposed to be an acoustic session because the place is so small, although we stretch a point for me on bass guitar, because there actually isn't room for a double bass (and my amp doubles as a seat!) A lot of the players are regulars, though we have an open door policy, and we try not to be too bothered about who plays what and when - generally the first person to grab a solo after the singing gets to run with it, and anyone who wants to start a song off can do so. Sometimes though you'll get somebody in who has absolutely no idea of session etiquette, or worse, is actually unable to play. Recently we've had some people who've played out of tune, at full volume, and all the time, even right on top of the vocals. I mean really disruptive, and with no sense of how they'e p*ssing everybody off. When I've tried dealing with them as one of the people charged with running the session I've had incomprehension, abuse, or on one occasion, threats of violence. Any of you gig warhorses had this sort of thing happen? How do you deal with it? All advice appreciated! Doug.
