Alaska Mike's version was one of the first songs I learned in my younger days, back about 1961. It was written by Fred Hellerman, using the nom de plume "Fred Brooks" (Copyright 1958 Sanga Music Inc.). Fred Hellerman was a member of the Weavers and you can find this song in THE WEAVERS' SONG BOOK (Harper & Bros, 1960), p. 162. The tune is very close to the traditional one. T.O.M.
