Gallis Pole ...

I first heard this by Led Zep, they recorded a version in Wales with a fairly bizarre video with one of their dogs running around ... and a hurdy gurdy ...

The English Folk Song and Dance Society in London has over 80 versions of this tune, also called 'The Prickly Bush' in archive, and Spiers and Boden / Bellowhead do a version on 'Bellow' (which is, incidentally, recommended by the EFDSS) - both are excellent.

The original has been transformed over the years, including by Leadbelly whose version  I believe inspired Led Zep. They gave the song a dirty twist at the end, ditching the original moral / happy ending with one where the hangman has his cake and eats it. I have remoulded the song from how I first heard it, and added my own tragic ending twist.

I welcome any comments!
