Number 329 in the Roud Folk Song Index. Sometimes considered to be an offshoot of The Two Magicians (Child 44), but this is doubtful. See also:

Sally My Dear. DT. No source is named for the text; the tune was noted by Cecil Sharp.

More verses to Sally, My Dear. Discussion with two further, unprovenanced texts.

Hares on the Mountain. DT. Source not identified; appears to be the set noted by Cecil Sharp from Louie Hooper and Lucy White, Hambridge, Somerset, 1903, with an additional verse tacked on at the end from somewhere or other.

Did Niamh Parsons mention where she got her set?

The text George found at Lesley Nelson's site (see above) is not related to this one.
