"Pop to trad

Green Fields of France"

Interesting point - I wonder if a song that refers to events in a specific period of modern history (in this case WW1, 1916) can be considered traditional?

I suppose if the author is unknown then yes. But if - as in this case - the author is known (and even still alive, as here) I'm not so sure (?).

I'm not disputing Barry's suggestion above, it just made me wonder. Any thoughts, anyone?
