Yes, I agree that some floor singers are crap. I was crap myself, in my earlier days. And now I'm pretty good. That's because I was not just tolerated, but welcomed, when I first started going to folk clubs.

That, to me, is the beauty of folk; everyone is given a chance. And if I sometimes have to endure a boring, tuneless performance from an inexperienced floor singer ... well, some generous folkies did that for me, once!
