Actually this thread has gone in a bit of a different direction - T's stuff is very informative and I don't recall it elsewhere (which doesn't mean it isn't there!!)

I just reread my last post and I think I sounded pretty severe - didn't mean it like that at all. I'm one of those souls who always looks in on the "what is folk/traditional" and "copyright" threads and don't mind it being rehashed at all.
