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.
