Ah, better details. That "leman-day" business I quoted from Gundry, getting on for 5 years ago in this very thread when I was quite the newbie, seems even less likely now than it did then. One thing, though; Frank Purslow had days when everything seemed to be Irish. Sometimes it was, too, especially in the cases of late broadside songs, often set by migrant ballad-sheet sellers to melodies familiar in Ireland; but not so very likely in this particular case, I'd think.
