James H: Nobody at the club says anything bad to her, a few suggestions have been made which have I think led to the small improvements we have seen, but we're worried that she is putting other people off from becoming regulars, because they don't want to have to sit and listen to her every time.... and given that the club only just has enough regulars and semi-regulars to keep going, we might not be going in a couple of years, let alone 20. What do we do???

James - I think you just have to bite the bullet and put it to her, quietly and privately, that she doesn't cut the mustard. It's really difficult, I know, and chances are that she will be very upset and feel put upon. But if the effect of her performance on the club is what you say it is, then it has to be done. It's very like telling a band member that he/she has to go because they're not suitable for the band - or telling a colleague at work that they have bad body odour (I've had to do that one in my time - and bloody awkward it was).
