You know, I don't think anyone's really tried to figure out what http://www.youtube.com/watch?v=HoSV1CERCr0 (skip to 2:44) part of the theme is in english. We know the "Dragonborn, Dragonborn, by his honor..." part. My take on it is:
And the Scrolls, have foretold
Of dark wings, in the cold
That when brothers, wage war
Unfuuuuuuurrrrlllll
ALDUIN, bane of kings, ancient shadow unbound
So, let's try to translate it!
