I remember him from Gerde's Folk City in New York around 1959-60. He sang a lot of Native American related songs. I always wondered if he was related to Oliver La Farge. That writer of Crazy Autumn, a book I read as a kid about two Indian children. I don't remember him singing traditional songs. I may be wrong but I always think of him as singing his own music.
Not much information but maybe it will get someone else's memory going.
