Very kind of you; I am sure that we are all glad that you are satisfied with our modest efforts.

However, if you are still here, I should mention that new information was brought to my attention by Steve Gardham shortly after my post here; my comments in this thread in re the earliest known appearance of the song in print are therefore out of date. For more information, see the new, revised edition of Marrow Bones (EFDSS, 2007).
