Thanks everyone! I've got a new perspective on the song now! Never actually saw the verse about the swords and I'd been under the impression that Matty was supposed to attack Lord Arlen with his pocket knife - which seemed a bit strange after the Lord had been 'honourable' enough to refuse to kill him naked. Incidentally, does everyone think the Lady is supposed to be the villain - Lord Arlen himself, though the wronged party, could still be seen as the evil killer!
