I don't know if its the same song, but there is a song 'The Furze Field' in the DT. Something is playing up at the moment and I can't find it at Mudcat (I am getting 'page not found' messages) but it is in the downloaded copy of the DT on my machine, so I assume it is here as well.

It's from the Gardiner collection and its in the 'Marrowbones' book from EFDSS.
