A Lyrical Mystery

Explanation: Sonic (who has had games with weird or muddled lyrics such as CD, Rush and Secret Rings) is trying to help Sly figure out the lyrics to this: www.youtube.com/watch?v=M9WZz9…

But seriously, can someone tell me what's being said here? All I know is that all the lyrics are in complete English as per information I saw on Wikipedia.
