Thanks for the background, Bennet. Would you happen to have an answer to my earlier question, namely, could Zeitlin and Secunda have based their song, at least in part, on an earlier folk song? Perhaps from a different culture in which "Dona Dona" had a meaning? It seems to me that that would be a great topic for an ethnomusicology research paper...if there are any ethnomusicologists out there.
