Sorry, one I missed
"Crap begets crap. Quality begets quality."
Crap certainly begets crap; put into practice a crap policy like 'you don't have to be a singer to sing at our club' and you are encouraging bad singers.
There is no evidence that quality begets quality; some of the worst singers I have heard actually believed they were good - even in the company of good singers. The lady I first described who was incapable of making two notes relate to each other pitchwise wrote to the club committee complaining that she was given only one song - how would you have handled that one?
