Most people I know are not hard-core religious people. They are what I would call 'lightly religious.' So I don't buy the notion that we can't laugh about religion in America.
I did an album a long time ago called 'Replicas ' which was entirely science-fiction driven or science-fantasy. Since then it's been a song here a song there. It's not really a constant theme. I've written far more about my problems with religion with God and all that.
