So? Ich dachte immer, es sei eine Anspielung auf die Toten, Hades, Überquerung usw..
Naja, wie auch immer... 
edit: Und ich hatte sogar Recht!

The ferryman in ancient mythology used to ferry the souls of the dead across the river. Some people think it was the river Styx or the river Hades, anyway it was the gateway to hell. And I tried to put together the idea of having a story with this wild horseman who is thundering through the night, heading for this river. And I can see it in my mind’s eye every time I listen to the song. And the river with the moon on it, and the ferryman waiting. Basically it is a story about destiny and the time when you have to make an important decision in your life. The word does not have any particular significance, apart from what I have suggested, ancient mythology. But also there are many many thousands of boats all over the world which are called ferries and I am quite sure they would have a ferryman involved with the movement of the passage of this boat or ship.
