Lyrics Is You Is or Is You Aint My Baby - Anita O'Day

Is you is or is you ain't my baby?
Well, the way you're acting lately, well it makes me doubt
You were still my baby, baby
But it seems like my flame in your heart, well it's just gone out

A man is a creature
That has always been strange
Just when you're sure of one
You'll find that he's gone and made a change

Is you is or is you ain't my baby?
Well, maybe my baby found somebody new
Or is my baby still my baby too?
