Hear that lonesome whippoorwill,
He sounds too blue to fly.
The midnight train is whining low,
I'm so lonesome I could cry.
I've never seen a night so long
When time goes crawling by.
The moon just went behind a cloud
To hide its face and cry.

Did you ever see a robin weep,
When leaves began to die?
That means he's lost the will to live,
I'm so lonesome I could cry.

The silence of a falling star
Lights up a purple sky.
And as I wonder where you are
I'm so lonesome I could cry.
