by running workshops we are applying standards,and hoping to improve standards.
this is what Bryan Creers club is doing,and that is very laudable.
I am sorry,I dont believe people who say that they will allow anyone to sing on a guest night,the person who is being honest here, is Dave The Gnome.
personally. I would be very reluctant to stop anyone from singing on a singers night,but I can think of about three people in forty years,who were so bad,that I would try to encourage them to have voice workshops,before I put them on again,one of the three was a recorder player with no sense of rhythm,again: first I would try[hopefully tactfully] to encourage them to go to a suitable workshop.
I wouldnt stop someone from singing because they were using words ,but I would try to encourage them to have a go without.
however I dont think singing with words is a very good idea.
In any club I have run I have never stopped anyone from singing.
