I'm coming a bit late to this but just found the discussion. I have the 78 record of Duna sung by Reinald Werrenrath and it has always been one of my favorites. I had it transferred to a CD but I wish I could find a copy that had been cleaned up. The poem is the original version.

On the record the song is attributed to Marjorie Pickthall and Josephine McGill. The number on the record is 844-B
