the success of a singaround is not about going round the room.. but going round the room and making sure a poor singer is followed by a good singer, so a thought out rota makes for a good evening.
Rigby i sing in folk clubs and also go out busking, when you go out busking you get an honest reception, i consistently make 30 to 50 an hour, but i practise, and was lucky to be gifted a reasonably good voice
