Oh Jack don't take on so! I only meant to suggest that it wasn't always necessary (or indeed possible, as some have pointed out) to play the notes as written, That's a very victorian concept.

Anyway-

Arbeau's dots may be the earliest version of this tune we have; but surely only represent how it was played in the ale-house where the tune was collected, or perhaps the interpretation of copyists? Which rather takes us back to the original question.

And without the discord (whether between instruments, or posters on mudcat). would it be folk music?
