MMario's click-on above takes one to texts and notes by Murray on Saltspring. There Murray notes the early versions of the the tune "Piss upon the Grass" = "Nancy Dawson" (Mulbery Bush) in connection with "Elsie Marley". ABCs of early copies of both are in file T1.HTM on my website (Mudcat's Links).

The song above is in DT file ELSMARLY with a different tune.

"Byker Hill" collected by Sandy Paton and recorded by Martin Carthy is also in DT.
