Ten years ago in this thread Charlie Baum wrote, "Charles Seeger (the musicologist) had a brother John, who was, among other things, head of the Fieldston School in The Bronx, New York," but I think that John was (is?) Pete Seeger's brother, not Charles'. Also, I think John was the head of the elementary school in the Fieldston system, not Fieldston itself (which ran from grades 7 through 12).
