Thanks for the comment on the Housman.

My memory of Go To Sea No More (I probably have a recording of it somewhere but can't remember just where) is that it is quite similar to The Flying Cloud air, but with a different meter. Thinking about it, it occurs to me that the melody of Dylan's I Am A Lonesome Hobo from the John Wesley Harding album is also quite similar.
