What does vonnegut use as the epigraph to his novel?

I believe the correct answer is "The cattle are lowing, / The Baby awakes. / But the little Lord Jesus / No crying He makes."

In the "Slaughterhouse-Five" Kurt Vonnegut uses lines from a Christmas carol "Away in Manage" as his epigraph:

"The cattle are lowing,

The Baby awakes.

But the little Lord Jesus

No crying He makes."

This epigraph is usually considered for a reference for Billy Pilgrim (or Vonnegut himself) as he saw horrible things, but complained very little.
