Every Brit has one of those in their back garden. We always arise at sunrise to worship the mystic spirits in order to bring good fortune each day.
Actually all is explained in 'Ashley Hutchings: The Guv'nor and the Rise of Folk Rock' by Brian Hinton and Geoff Wall:
On the back cover of the vinyl edition of Liege & Lief is a carved wooden totem owned by Dave Swarbrick, impossibly ancient - like a cross between a scarecrow and a human sacrifice, next to the Witchseason logo, and surrounded by a circle of flowers and leaves, a ribbon bow no less. "Dave Swarbrick found that in a churchyard," Ashley explains. "He found it amongst leaves and things, and it was rotting away in some sacking, and it is quite clearly some magical totem of some description. And we thought that it was just very suitable, and as you well know this and Full House are absolutely shot through with magic and mystery, both albums, and so we put it on the album. But Swarb found it."
