In it's first few years, this was one of the best things on television, ever. I liked Leonard Quinhagak, the progressive shaman. A recurring character played by Graham Greene. Of course the whole damn town was great. The only part that ever got tiresome was the running sexual tension between Maggie and the Doctor. Jeez! Just DO it already and quit bitching at each other so we can get on to the more interesting characters.

Hope TV cycles back to making quality shows like that again soon... though I do like "House".

And Giok, the tune you are thinking of was called "Ojibway Square Dance", recorded by Georgia Wettlin-Larsen and one version (called there "Turkey in the Straw") can be found on this album.
But the version from the show is on this one.
