In honor of 6-6-06, we give you the devil's own band and the authors of "6-6-6, The Number of the Beast": Iron Maiden. Enjoy the rest of your last day on earth to the tunes of the band's trademark galloping guitar riffs. (If it sounds like Mongols on the ride, it must be Iron Maiden.)
Yes, that's two YouTube posts in one day. But who are you to argue with Bruce Dickinson?
