Thread linked by Giok (47505) is linked at the top of the page. The other main thread, 42808, which I linked, needs to be placed there as well.
See "A Sailor Courted" in the DT and Malcolm's post in thread 42808 where he links to this song in the DT but uses the title "The Constant Lovers," in his post, and also links to "As I was a-walking down by the sea shore," also called "Constant Lovers;" he points out the problem with the name.
The former (A Sailor Courted) is called "The Constant Lovers" in the Bodleian Library. The Contemplator doesn't seem to have the tunes. Two tunes are given in 42808 but neither may be what you are looking for. The DT midi for "A Sailor Courted" doesn't work.
