I'm pretty certain it's an American ecotype most closely related to The Butcher's Boy, though it has been found latterly over here, just like the ecotype it shares its tune with,'Died for Love' again an offshoot of The Butcher's Boy. the version above is all floaters from a variety of sources, but all being traced back to either 'Brisk Young Sailor', or 'Waly waly'. Bob has it pretty much covered.
