The lyrics you guys are coming up with are so off beat...
They actually aren't. The real song has syllables alternating between 5 and 6. Other than one line, that's what these lyrics do too. It's a going to be a little hard getting it to work with the instrumental, since the instruments play a different melody than the voices do.
edit- well actually, now that I look at the instrumental and the lyrics at once, it doesn't seem hard at all, I think we're ok.
