Thanks to all who helped out and developed the thread, I am still left with a feeling that somehow the "Derry" lyrics are near but the repeating refrain,"the very next step he took up the ladder, (which I assume is the gallows) is the key to this what must be a "Croppy Boy" version. I have asked Barbara through her page, we will wait and see.
Once again thanks to Sorcha, Kevin and Noreen.
