Billie Holiday, "Do Nothing Till You Hear from Me"

And far into the night he crooned that tune.
The stars went out and so did the moon.
The singer stopped playing and went to bed
While the Weary Blues echoed through his head.
He slept like a rock or a man that's dead.
        - from "The Weary Blues," by Langston Hughes
