Thanks for the abc, george, but when I converted it to standard notation, it was pretty daunting. All those dots!

I found a page that offers the modern 4/4 version and a 3/4 version from 1926. (The links are at the bottom of the page.) So much for all the debate on what time the song is in; we can swing either way. Here's the link:

As for origin, it suggests that it may be a Dalmatian fiddler's tune. I like it!

This is a beautiful melody. Thanks to all who brought it up.
