Sorry! The confusion is my fault. Mark Knopfler wrote the song and had a tune, of which I know nothing. Dublin singer Gerry O'Reilly, at the suggestion of Terry Moylan (author of The Age of revolution in the Irish Song Tradition ), fitted it to an old Irish air usually known as Amhrán na Leabhair (song of the books - another story). Niamh Parsons heard Gerry singing it and recorded that version. Several other traditional singers now use that version
