'I am arguing about (a) The dishonest practice of filling a folk club evening with songs that are patently not and (b) Seeking to de-define folk song, without explaining exactly what you mean by folk.
You know as well as I do what folk is, at l;east, when I have asked for an alternative definition, you nor anybody else has come up with one - not one single person.'

Proof certain that Mr Carroll is not on the same planet as the rest of us, Although you can't argue with the last line, that's absolutely correct, it's not 'one single person' that has come 'alternative definition'.... it's hundreds!
