The Sandman’s coming in his train of cars

With moonbeam windows and with wheels of stars.

So hush you little ones and have no fear,

The man-in-the-moon is the engineer.

The railroad track tis a moonbeam bright

That leads right up into the starry night,

So put on your ‘jamas and say your prayers.
