Here is an abc for the tune as I know it. It's similar to the "Nancy" one but not quite the same.

I don't know how long it will last there but I have posted this abc to our test song here. You can get the tune in MIDI, png graphic and pdf formats from there (at least until it gets replaced with some other abc).
