Song: The Gaelic song is a version of Café del Mar's "Light of Aidan - Lament", which is much more lighter and softer. I do not have or know where to get this version.

Lyrics: "And my army of brothers went over the hilltops, drenched in blood we may be... but fighting is all left to me... Together with my army of brothers... down we fall... darkness in all... through hell!"
