I can trace this song back another four years, to the Druids' 1970 album Burnt Offering; here's more about the album and here's the track on Youtube.

It's about the hunt of a hare by a Nottinghamshire bus driver (the bus is going from Hucknall to Mansfield); despite the woo-ish spirit of the season stuff on Properganda, I think it's more or less a joke song. Presumably it was written by John Adams, as he seems to be the link between the Druids and Muckram Wakes.
