Barney's outro to Vanishing Point, 28 Apr 89 Universal Amphitheatre, mentioned something I had not known prior to listening to this.
BS: "Thank you. This will explain something about that song. Whistle Down The Wind was a film, a movie, about uh, an escaped prisoner, who thought he was Christ."

This gives more hints on Bernard's feelings on religion, as if Sunrise wasn't clear enough.
