There was a rendition on an Irish Rovers album sung to the tune I know as Butchers Boy. But it's called "My Boy Willie" Tells the tale of a young man who goes to sea wearing a special coat. After a time, his girlfriend goes to look for him Oh Father Dear, build me a boat "That on the ocean, I might float" She asks after him on every ship she passes, and is finally told a guy with that coat drown (of course)

This was a "party piece" for one of the Ir. Rovers, meaning at a family gathering, no one else would have the poor manners to sing it before your turn. Anyone want all the lyrics? I have them somewhere
