The title of Maid Freed From The Gallows doesn't give the game away - because the song has no title! I.e. no traditional singer would announce 'I am now going to sing The Maid Freed From The Gallows'. They did not generally speaking know songs by title. If they knew them by any 'title' it was usually the first line. Hence the early collectors who used to ask 'Do you know a song that starts As I Roved Out One May Morning?' Usually got at least half a dozen hits! Titles are a result of collectors and editors.
Anyway, call it The Prickle Holly Bush and it gives nothing away!
The chorus is a different kettle of quorn because that is integral to to the song. Just to show I can contribute something positive what about Sweet Fanny Adams?
Shall I never see you more sweet Fanny Adams?
You're the daughter I so dearly did love.
You were killed and cut to pieces by a villain.
But now you're in heaven up above.
