Jean's lovely tune reminds me of the tunes I've hear to 'Lord Thomas and Fair Eleanor'. I can't hear a resemblance to Motherwell's. Her tune is in Bronson's Ab group of 15 versions mostly from the Appalachians. If you're interested in the tune families to the 74 versions of the tune he gives, reading his headnotes would be a must. They don't mean much to me as I don't understand the technical language used. He does tentatively make a connection of one branch of the American tunes to the Motherwell tune.
