Hi Charlie, maybe you might PM Liam'Sister In Law (by way of Laim's Brother. I know Bonnie did quite a bit of good research on the songs that they recorded & wouldn't be at all suprised if her's isn't direct from the Carpenter collection which she is familiar with. The small bit that I have can be found in Hugill's Shanties from the Seven Seas (5 versions/variants), Harlow's Chanteying Aboard American Ships (2 versions), Colcord's Roll & Go (1 version) & Abrahams's Deep the Water Shallow The Shore (2 versions). Abrahams has his from the Isle of Nevis used for rowing & of West Indian origin. Hugill has all of his as negro in origin & all used at the pumps, though he also says it later was used as a capstan but gives no example of it in that form. His 1st version is also from a Welch sailor. Colcord also has it being used at the pumps. Harlow has both his versions, again used at the pumps & being "pureeely English" with the 2nd version being used by "Badian Negros" at the falls. The Johnson Girls have it being sung as a capstan shanty & I'd say that is where the difference between their version & most of the more commonly sung/heard other versions. Lastly all of the versions I point out sing of different parts of the ship where the fire might be located in the J-Girls the references are unreleated to any fire.
Don't know if any of this shed's a little more light on what you're looking for or if you already knew this (in which case you should slap my face) but there you go anyway.
