In The Wee Small Hours of the Morning is a song composed in 1955 by David Mann, with lyrics by Bob Hilliard, and was the title track to Frank Sinatra’s album by (nearly) the same name.

The lyrics are divinely succinct:

In the wee small hours of the morning,
While the whole wide world is fast asleep,
You lie awake and think about the boy
And never, ever think of counting sheep.

When your lonely heart has learned its lesson,
You’d be his if only he would call,
In the wee small hours of the morning,
That’s the time you miss him most of all.
