I can't claim any scholarly research on this but my memory is that when Paul Brady arrived back from the States to join Planxty in the mid '70s, he used to introduce this as 'Arthur Mc Bride & the Sergeant' as opposed to the previous Planxty version sung by Andy which was just called 'Arthur McBride'.I definitely remember him referring to it as a version of the song that he collected in America. Whereabouts I don't know.
