The Bonnie Wells O' Wearie

The Wells of Wearie, above, is copied here with no acknowledgement of any source, so I had better provide the missing details, insofar as that is possible.

The text appears to come from  http://www.jigheads.com/, the website of American performers Kim McKee and Ken Willson.

They themselves credit no source of any kind for the words they publish: as it happens, these are a shortened form of the text appearing in Child, English and Scottish Popular Ballads, as example B of group number 4, 'Lady Isabel and the Elf-Knight'; but with various alterations made by somebody or other; perhaps McKee and Willson, but for all we know it could have been the fairies at the bottom of the garden.

I don't know where they got their tune from; none is known for this variant. Perhaps they explain in the sleeve notes to their recording?
