The DT gives the maker of the song as Peadar Carney. It was, of course, Peadar Kearney, uncle to the aformentioned Dominic Behan. He also wrote the great anti-recruiting song, The Recruiting Sergeant. And the National Anthem. The Irish National Anthem, that is.

The DT version of the song mentions "Bunker Hill". My memory tells me that it should be "Pieter's Hill" a reference, I think, to the Boer War. The Boer War would probably be more relevant to Irish republicans of Kearney's generation.
