Joe,

I don't have the text at hand to make a side by side comparison, but the DT text for this song has the unmistakeable marks of Stan Hugill, so it is probably either from _Shanties from the Seven Seas_, with or without a few changes from an individual who ultimately got it from there.

Hugill's version in SfSS would have been a composite, compiled and arranged out of verses he'd seen in print and, likely but not necessarily, some he'd learned in the oral tradition, and some he made up (or fine-tuned) for publication.

To get to Hugill's version, one has to go back over many many prior printed descriptions of this, which vary considerably, and deduce/speculate the sources. For practical performing purposes, probably just better to develop one's own version, since there is no "definitive" version whatsoever. I realize you used scare-quotes on "definitive", meaning you know the idea is problematic already. So here's one person's opinion that, I think, it is truly too problematic in this case to be a useful concept.

One approach, however, could be to survey the documented versions and maybe pick out the most commonly attested verses. Or, maybe, toss out the verses by "disreputable" sources? Perhaps if I and others have some time, we can trace out the sources, but that might be rather academic rather than practical.

OTOH, knowing what Jon Boden or Louise Killen have sung, IMO, doesn't tell us much so far as their version probably ultimately go back to a book or recording, that we could look at directly.
