You weren't alone as evidenced by the roar of the crowd everytime that line came up. For many years, it was just wishful thinking.
Along the same lines, at New Haven, 4/22/83 (one of the best show's I've been to, especially the first set), the 2nd song was Bird Song.

Just in case you didn't know.......
