Villan,
Perhaps I didn't make myself clear - I am not a performer these days. I am therefore in the same position as the Countess, with no vested interest, other than an empathy with performers.

I'd like to see you have a full house paying at least a fiver a head - that way you could think about having more than one guest, a larger combo or possibly a Big Name.

On the other hand, as someone else has said, if you can satisfy your members and the musicians at £2.50 a head good luck to you, although I think that's a short term position.
