Where did Jim Carroll get the extra stanza? It's posted online after a version he collected. The version I have doesn't have that stanza.

My three Harry Cox versions don't have it either. But a very similar verse is in versions sung by A.L. Lloyd, Shirley Collins, Anne Briggs and Martin Carthy. Carthy noted that it "is another song from the Norfolk collection of E.J. Moeran with an additional verse" but didn't say where this verse came from.
