At the time it's written, it was the beginning of our career and with every song we're thinking, 'This is what's creating us.' Now, nothing is creating us. We're well-created. We're there. It becomes just pure pleasure and you become sort of an archeologist of your own music. You don't judge it, because what's the point? It's a 30-year-old song. It just becomes fun.

Led Zeppelin is just a bunch of stupid idiots who wrote cool riffs.
