Mood Indigo

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'"
I always get that mood indigo
Since my baby goodbye
In the evening 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

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'"

as sung by Ella Fitzgerald.
