"Ticket to the Moon"

I figured out the chords for "Ticket to the Moon" last night and noticed an interesting feature.  As I noted before, each phrase in the vocal melody in the chorus ascends, giving an impression of taking off and going to the moon.  The chords, however, descend.  It's a repeating progression of D minor | C major | Bb major | A major.  This opposition between the descending chords and the ascending vocals illustrates the narrator's conflicted feelings.  He's obligated to leave ("I paid the fare; what more can I say / It's just one-way"), and yet he would rather stay and "see the sunrise / In your eyes."  The opposite trajectories of these musical elements demonstrate that he's pulled in two different directions.
