At 144 bars this is quite an epic for a songbook piece. I originally discovered this in a loose collection of old songbook music.
Jozsef Gregor informs me that this is, in fact, "Régi táncdal" ("Old dance song") from Hungary, and is a very common and popular song for Hungarian choirs. The original melody is "Ungarescha" from the J. Paix organ book (1583), and the present four-part arrangement is by Hungarian composer Lajos Bárdos, with text written by Karoly Varga in 1949.
Here are midi (computer music) files for you to download and listen to (If you're using Microsoft Windows, simply click on the link and they should play automatically. If you're not using Windows, I'm going out on a limb and assuming you're technically competent enough to figure things out for yourself....).
Also note that there are midi files of each individual voice part for each piece, so you can hear what each one sounds like - especially your own!
These midi files should give you a fair idea of what each piece - and each individual voice part - sounds like, especially if you're unfamiliar with reading music.
And for those that would like to dowload a viewable and/or printable copy of the score (HINT: most people will want the PDF file; don't try to view the Postscript file unless you know what you're doing):
