I do not wish to exclude non-traditional songs from the clubs - show me wheer I hav ever made such a claim

"Why on earth should anyone want to define it!?"
Because some of us wish to discuss it as well as perform it, and others of us want to turn up at a venue to find that what is on offer is what it says on the tin.
(A bit of an aside, but if I picked up a tin in the supermarket and it said "The contents loosely conform to soup" I think I'd put it back.)
You've been saying very much the same for years. Go back and read your own posts.

What I Hate Mondays, The Birdy Song, Freeborn Man and Willie McBride have in common is that none of them are folk songs according to the definition you cling to. All that separates them is personal taste. I chose The Birdy Song for its obvious absurdity. (You seem to be far more familiar with the words than I am.) By your logic it is just as acceptable in a folk club as Freeborn Man. Your taste, my taste, Dave the Gnome's taste, Raggytash's taste and Big Al's taste are equally legitimate. Nobody ever pauses to think, before singing a song or booking a guest, "Will this meet with Jim Carroll's approval?". As you said, "Can I just add to this is that what runs through these arguments like 'Blackpool runs through rick' is that our definition of "folk" should be based on personal tastes rather than what it is.
This is nonsensical ..."

THis is the type of behaviour that turns these discussions into slanging matches... I suggest you go to the dry cleaners and get your cloth ears sorted out
I'll leave you to set the standard of behaviour shall I Jim?
