Yes, I am aware of that, Willa. The "back against an oak" verse finds its way into many, many songs. Thanks for the Peggy Seeger version. That doesn't look like the melody that Herbert Hughes collected in Ireland and published in 1909. I sing the tune Hughes published on the mp3 linked above. This version about being battered is very interesting to me. It's worth noting that the song Hughes collected in Derry was written as a man singing it.
