Hi,

In "Songs and Ballads of the West: A Collection Made from the Mouths of the People" by Sabine Baring-Gould, 1892, he comments:

No two singers give the same ballad exactly alike, the variations are sometimes so great that we suspect they are reproductions by local poets of the old themes. A striking instance of this is “The Masterpiece of Love Songs," that was printed about 1670; and has been reproduced by Mr. Ashton, in his “Century of Ballads.” I have taken down one form of this, tolerably like the earliest printed form. It exists as a modern broadside in another. Mr. R. N. Worth has sent me another taken down from an old man of 87 quite different, and I have had a fourth also different from another singer.

Notice that here (Songs of the West) Baring Gould claims to have taken down "Masterpiece" but in his MS it's attributed to Bussell. The other singer is Sam Fone and his version's melody is given under Masterpiece with no text.
