Information from Reinhard Zierke's English Folk Music Website (which is a great source for Carthy's lyrics):

Sung by the Three City Four (Martin Carthy, Leon Rosselson, Ralph Trainer and Marion MacKenzie) in 1965 on their album "Three City Four." This track was re-released in 2001 on the anthology "The Carthy Chronicles." Leon Rosselson recorded this song himself on his albums "Palaces of Gold" (1975) and "Perspectives" (1997).
