What "traditional Neapolitan song" is the basis for the song Un Monde Parfait?

I have no interest in listening to and then comparing songs, but here’s a list of traditional Neapolitan songs.

@syz Thanks for your help. I’ve pretty much given up at this point, but I did find some nice sounding Neapolitan music.

It is a catchy tune, and a fun little toon. It does have a traditional french sound, but nothing I could recognize.
How can this not be about ice cream? Parfait… Neapolitan…Those dancing cows…

This article (in French) says it was written by a Frenchman living in Naples.

Then it would qualify as Neapolitan, I guess.
