I like the 'toll the bell' verse - it's another one that Shirley Collins revived for her version. We don't hear it much, despite it being in Purslow's Wanton Seed version; I guess people find it anticlimactic.

I don't immediately recognise all those sources, but I'm curious about verses 10 and 11, as well as verse 6 (baby is delivered); I haven't seen them in any English versions apart from Baring-Gould's, which I don't entirely trust.
