"according to you, wanting to sing immediately disqualifies anybody from being capable of doing so."
Where have I ever said this?
Therefore you are giving your club over to anybody who walks through your door, even after they have proven themselves incapable of singing - and you have no facility for helping them because they are too few in number (I paraphrase").
"How are we supposed to know before we put them on? (He asks for the umpteenth time.)"
Also for the umpteenth time - been through this and you continue to wheedle round it.
Once someone has shown shown themself unable to sing, but willing to do so, you offer them help, rather than your policy of continuing to put the in front of an audience to flounder and drown. That is what any club I have been involved in has always done - that is what your club does not do.
You have moved from your original position of saying that poor or non singers DON'T turn up at your club asking to sing to admitting they 'occasionally' turn up. What did you do when they did?
You sound far luckier than many of the clubs mentioned on this forum who do have problems - wonder if you overawe them into silence; you apparemntly offer them no assistance to improve - or have you been hiding your light under a bushel.
