And for modern retold lyrics, get hold of a Heather Alexander tape with "Black Jack's Lady." I can't post full lyrics, but it tells what happens AFTER the lady who ran off with the gypsy Black Jack Davey found herself abandoned the next day.

She rides after him, sword in hand; kills men who accost her; meets Davey in battle; and her spirit still rides through the hills dealing vengeance to unfaithful men.

~Young men, be true in the loving you do
Or else may the Gods have pity on you
If you meet with the Black Jack's Lady.~
