I'm not sure you can draw any conclusions or make any generalisations about the topic of this thread. There isn't enough to go on. I'm very suspicious of singing being described as "bad" – singing more than any other musical practice actually – because personality and taste have so much to do with that.

For instance, there are plenty of big name folk acts who I think make utterly boring, tedious music. They are "bad" singers (though I wouldn't use that word excatly) in my book because they are bland, and characterless singers. If anything, I'm more likely to enjoy a singer who others would think of as bad – I'm much more a fan of a rough, grainy, wayward voice.

So, in contrast to some of the other responses to this thread, I'd like to know who the performers were. Send me a private message if you like – I promise not to tell anyone. But I'd like to know - just so I can check out their myspace page and decide for myself whether they "can" or "can't" sing.

Secondly, having promoted several nights myself, I'd be very wary of forcing a band offstage - whether they were paid guests or not. I really don't like that idea. If they're drunk or offensive I might make an exception, but if it just comes down to music then I think the audience will vote with their feet. If an act totally loses the audience, well, the act will soon know about it... I mean, if I don't like an act, I just go to the bar...
