thecoombes has put his finger on it - a concert club should primarily be run for the benefit of the audience, not the performers. Singers' clubs and singarounds are the reverse, and there it is entirely appropriate to encourage novice singers, but anyone aspiring to play support to a professional guest should have reached a certain level of competence. I think he has the right approach, for the type of club he is running.

I also welcome that he is prepared to give visitors priority over regular performers. So many clubs feel they have to let their regulars sing and will only fit in a visitor if there's time left over. As an audience member I would prefer to take a chance on a visitor than listen to a regular (no matter how good) who I heard last week and will hear again next week. As a regular floorsinger, I was always willing to stand aside in the knowledge that I could get a spot next time.
