Then I looked a little closer and listened to the second verse, which I'd never really paid attention to before. It's all about a man asking a preacher to help give him strength to keep on fighting the man, and the preacher telling him to grow up instead.
That is a really brilliant tie in with the episode. Bill and Eric are caught in what is basically a religious war, and they're concerned only with living their lives. The authority they're standing up to is not only the Authority, but anyone who is standing in the way of them simply conducting everyday business.
And yet, the Authority is actually pretty cool. They recognize that existence with humans is the only option, if nothing else because we massively outnumber them, and they're mostly mad at Bill and Eric for jeopardizing that. Bill and Eric believe in their mission, but they still make it clear that they want control over their own lives.
So like the song says, "I fight authority and authority always wins," but in the end Bill and Eric are still walking away. So we'll see, won't we?
