Bruce O, From Hugill's Shanties Of The Seven Seas, he has it as a capstan shanty on Doeflinger's word (who has it as The First Of The Emigrants, in his Shantymen & Shantyboys) who has it reported to him from Captain Tayleur. A few things very singular about this song are the place names are not ment to assist the memory in navational aids as in other sea songs (say Whip Jamboree or Spanish Ladies), for use in the piloting or costal navagating of a vessel, & it was usually sung outward bound, the sailors singing it to comfort the departing emigrant, an unusal expression, towards the passangers, in songs sung by sailors.
