Steve, There have been several attempts on here to define what "traditional" means. Not sure there'll ever be a consensus, and you're right, the question is complex, and I agree that it's not about the provenence. But I *have* seen people arguing here that if authorship is known ,then it's not "trad", so was just pre-empting that faction in my post above.

It wasn't *my* question though! I was actually just trying to get the thread back on track a bit as it seems to have deteriorated well away from the OP's question, into personal sniping and squabbling about semantics. Which may be rivetting for the 3-4 people actually involved in the exchanges, but is deadly boring to me, and, I suspect, others.
