So when was the last folk song written, Jim? If it's no longer happening, there must be a finite date when it stopped.

I agree that folk is not a style, but I disagree that folk songs are not still being written. They are the songs that people write about their everyday lives - for instance, I mentioned Ray Hearne earlier. The songs he writes about the steel and coal industries of South Yorkshire that he worked in and the impact that their closure has had on the local communities are, to my mind, definitely folk songs. Still, I don't suppose we'll ever agree on that.
