He had not heard them sing before.
"Now," he thought, "I shall know what kind of nonsense the angels sing when they are merry.

They don't drive cabs, I see, but they dig for stars, and they work hard enough to be merry after it." And he did hear some of the angels' nonsense; for if it was all sense to them, it had only just as much sense to Diamond as made good nonsense of it.

He tried hard to set it down in his mind, listening as closely as he could, now to one, now to another, and now to all together.

But while they were yet singing he began, to his dismay, to find that he was coming awake--faster and faster.

And as he came awake, he found that, for all the goodness of his memory, verse after verse of the angels' nonsense vanished from it.
