Actually, I've just listened to the song multiple times--what is shown all over the internet as the lyrics is "even the end of the world is a big dissapointment.
even the end the end of the world will be a let down."
After reviewing the song, though, the second line just doesn't seem right. Unless Guy's accent is throwing me off (it's possible, I'm not one-hundred percent familiar with English accents being a good old-fashioned ignorant American,) it sounds like he's instead saying, "even the end of the world will dawn on a let down." If I'm wrong, by all means correct me, but 'will be' just does not sound right.
(This is the Noisebox version of Theme From Munroe Kelly, by the way. I don't know if future versions even have lyrics.)
