Have great respect for Liam Clancy- a man with a gift for communication- I first heard it from Ray Fisher in the sixties, and she used the standard tune.
There is a recording by Frank Quinn, who left Longford to work as a policeman in New York, and put out a 78 of this song in 1925 with the same tune. It's quite likely that, if the song wasn't already in the Clancy family, Liam heard it on a 78- less likely that Ray had heard Frank Quinn's version at that time.
Frank Quinn's 78s have been available on CD for many years on the Arhoolie label from the U.S.
