Lyrics:

You ain't been blue; no, no, no.
You ain't been blue,
Till you've had that mood indigo.
That feelin' goes stealin' down to my shoes
While I sit and sigh, "Go 'long blues".
Always get that mood indigo,
Since my baby said goodbye.
In the evenin' when lights are low,
I'm so lonesome I could cry.
'Cause there's nobody who cares about me,
I'm just a soul who's
Bluer than blue can be.
When I get that mood indigo,
I could lay me down and die.
