Thus they’ve made it permissible to rock out to songs about Middle Earth. Elevating everything you touch is all part of being a rock star; it’s what separates the mere mortals from the golden gods. It’s what has allowed Led Zeppelin to remain part of the cultural vocabulary long after they’ve ceased to be a functioning unit.
