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
