In another Mudcat thread a strong (I think) argument was developed that the singer Oscar Brand developed "the captain's daughter" and other hootenanny verses on his 1960 album.

Some years back I updated the Wikipedia page for this song by inserting several historical points about this song, especially distinguishing its form "as a shanty" and "as a popular song."
