Oh and another thing- no criticism of anyone was intended or implied. If you run a club where you only allow unaccompanied singing, instruments of any kind are barred, and you only accept songs, the exact provenance can be unequivocably be verified, that's fine by me (though you won't find me in there!)

In short, I'm interested in other people's views; I may or may not agree with them, but we're all entitled to our own opinions.
