The poem
You were glad to-night: and now you've gone away. Flushed in the dark, you put your dreams to bed; But as you fall asleep I hear you say Those tired sweet drowsy words we left unsaid.
Sleep well: for I can follow you, to bless And lull your distant beauty where you roam; And with wild songs of hoarded loveliness Recall you to these arms that were your home.

This poem was set as a song, but I can't remember the composer -- sound familiar to anyone? It's a great song, in kind of a bolero rhythm...
