SONG ID: What is the Hawaiian sounding song from Wong Kar-Wai's "Days of Being Wild"?

Can't find the name of this anywhere. It's the Hawaiian/slack-key instrumental that plays over the opening, over the slow shot of the jungle. I've heard it referred to in corners of the internet as a Django Reinhardt song, but nothing mentions a song title. It doesn't really sound like Django, anyway. It's a beautiful, beautiful song, and I need to find out what it is. Any help is appreciated!
