Bryan and Steve, thank you, you are both absolutely right, it will never sink in. And Steve, I'm happy to go with your definition, not too dissimilar from my own from what seems like several years earlier in this thread, where I said that a new song can be folk if it is influenced by, and respects the tradition of it's country or district of origin.

'fraid to say though, I expect Mr Carroll scared off the OP a long time ago!
