For what it's worth, Pete did a recording on Folkways Records in 1955 called Bantu Choral Folk Songs. I've heard that you can get all the old Folkways records through the Smithsonian, but I haven't tried it. He also did a book by the same title for Schirmer Pub. in 1959, which might help with spelling, etc. Those songs are a treat. I pulled this from the Pete Seeger appreciation page, but I forgot to copy down the addy - sorry - it was the first site listed on Google. Perhaps e-mailing that site could get you what you need.
