Classic Poem

How could I sleep so long;
The moon was low;
How could I close my eyes
On shadow, star, and skies,
And never know
The soft air held your song?
How could I sleep so long,
O Pierrot?

To-night I do not sleep;
The moon is low;
Beside my casement wide
I watch the shadows glide;
So long ago
You sang—alas, I weep,
To-night I do not sleep,
