For concerts which are held on a Saturday evening I charge £5 and just occasionally (once) I have charged £7. I generally book single performers for that like Allan Taylor, Bob Fox, Martyn Whyndham-Read, Derek Brimstone, Pete Coe and soforth. I never book an A Capella singer and won't (at least I am honest about that).

For my normal Friday, variety evening I charge £3.

I get more people on the Friday evening from the Village than Saturday. The village people wouldn't know any of the performers on a Saturday night, including Vin Garbutt :-)
