I thought that too, he kind of went on to say it was tweaked after with some lyrical changes but the track is from when they wrote it. But, I'd have to listen closer, I feel like the entire song was re-sung later.

Was the riff changed? I notice the first one strums it a bit different but for the most part it 's the same idea.

EDIT: I've heard/read Jon say the "Now you have my attention" line and it's absolutely a douche thing to say.
