Earlier i anonomously put a comment on the are you listening part of the wiki as i couldn't log in due to school computers. Me and my brother have had the thought that maybe we are listening to the lyrics not the words. If this confuses you let me explain.
Lyrics: This is what we have been told is sung even though it might sound different
Words: What it sounds like being sung these aren't always the lyrics
Me and my brother are about to begin listening to every song involved to see where the words are different to the lyrics and i will post our findings here.But not the silly things only the sensible things.
