GSS,
Wow, you are really fixated on this. Why is it so important to you? For the tenth time, would you book a heavy rock act into a folk club you were running? Would you want to perform folk music in a heavy rock club?

For the record, I would make a terrible policeman, since I am an inveterate rule breaker. I still wouldn't want to play my guitar in a singing-only club. There's breaking rules, and then there's being a jerk (as in complete and utter arsehole). Please note that I've never said I agree with a singing-only policy. I don't, actually. But it's THEIR BLOODY CLUB! They get to do what they want, and their audience apparently likes it. Why is it any of your business? Oh, sorry, I've asked you that several times already without any answer, so forgive me for wasting your bandwidth once again.

As for my intelligibility, go find an English teacher and show them my posts and yours, and see what they have to say about clear writing. And reading comprehension. You sound like a pot calling a stainless steel pan black.
