Something made me go Hmmmm... yesterday.

I was listening to the first disc of Nostradamus last night, listening to Prophecy and reading along with the lyricbook. While reading, I notice that a couple of lines were absent in the song:
Many years ago a boy was born
A boy with the gift
I wonder why those lyrics are in the book but not in the song? Last-minute song editing, maybe? Hmmmm...
