Is You Is Or Is You Ain't (Ma' Baby) Bing Crosby and The Andrews Sisters (words and music by Billy Austin and Louis Jordan) Is you is or is you ain't my baby? The way you're acting lately makes me doubt Is you is or is you ain't my baby? Seems my flame in your heart's done gone out. My friends say I could do a lot better, If this keeps up I'll soon need a nurse. I know I can't do any better, But believe me I could do a lot worse. Is you is or is you ain't my baby? The way you're acting lately meakes me doubt. Is you is or is you ain't my baby? Seems my flame in your heart's done gone out. When the moon goes down in the dawning And the sun comes up in the morning, Don't let the sun catch you cryin'. When the moon goes down in the dawning, Don't let the sun catch you cryin' if your baby don't want you no more. From: "Montcomags"
