None of the versions I have come across have a tune included. If the fiddle tune fits then it would be at least a semantic match. Do you know anything of the origin of the fiddle tune that would make it plausible. The notes by Rickaby especially, indicate that the song was not all that common. As to the meaning, I can envision it relating in some way to keg stoppers or perhaps it has some bawdy implications, but I am only guessing.
