The Huon Carol is a lovely but simple tune, and it is (loosely) based on an American Indian rhythm.

Some of the Christmas tunes from previous centuries would be nice e.g. Coventry Carol, with its very unusual melody, and some others whose names totally escape me - dang-it! The Holly and the Ivy (is that right?). I have a book buried in the depths of my music collection with some of those. I'll have to hunt them out for you.
