Mood Indigo (Armstrong Louis)

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
