Mood Indigo 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 evening when lights are low
I'm so lonesome I could cry
'Cause there's no body 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.

You ain't been blue,
No, no, 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 in and sigh
Go long blues.
