On the sleevenotes to June Tabor's Airs and Graces album, "Waly Waly" is credited as Child 204 (Jamie Douglas), which of course is where it's from.

However, the version June T. sings doesn't correspond to any of the Child 204 variants, and seems to have been put together out of bits from four or five of them. (Very effectively, too - this isn't a criticism.)

Do we know if the editing job was done by June Tabor herself, or if she got her version from another singer?
