We opened the door
To see the coming of the trains
Across this land of plenty
We suddenly saw
The ghostly horses of the plains
Their saddles empty
Struck to stone beneath the moon
These figures still remain
Steal your chances someday soon
You may not pass this way
Again [ Lyrics from: http://www.lyricsmode.com/lyrics/a/al_stewart/ghostly_horses_of_the_plain.html ]
