I always interpreted "Is there a storm comin', or are we just another shower?" as a reference to revolution. Is this generation going to change something in a storm, or will it just be another ineffectual shower. "I would have kept you free from harm, rang the bells or raised alarms, I would have kept them all at bay, except I thought I heard you say, you're the leper boy, you can't come in" seems to mean there always people trying to change things, but they're always rejected.
