Cover art for Ticket to the Moon lyrics by Electric Light Orchestra

On the superficial level, this is, amazingly enough, about a guy who ends up having to leave his girl behind and go to the moon - a one way ticket, so chances are it's a prison isle type thing a la Australia?

On the actual meaning level, it seems to simply be about a guy who is, due to unfortunate circumstances nevertheless outside of his control, forced to break off contact with the person he loves.
