Thanks Malcolm - I never thought to look in the Oxford Book (should have looked at Roud!). He does indeed use two different texts in the two books, though with the same tune. The Ballad History version was a broadside issued by "Oxlade, Printer, Portsea" (adding that Portsea is now called Southsea) and taken from W.H.Logan: A Peddlar's Pack of Ballads and Songs, Edinburgh, 1869.
