I'll be in my room alone   Every post meridian   And I'll read my diary   And that book by Mister Gideon      Bye, bye, baby   Remember you're my baby   When they give you the eye   And just to show that I care   I will write and declare   That I'm on the loose   But I'm still on the square      I've been lonely   But even though I'm lonely   There'll be no other guy   Though I'll be gone for a while   I know that I'll be smiling   With my baby by and by   With my baby by and by      I'll be gloomy   But send that rainbow to me   Then my shadows will fly   Though you'll be gone fo a while   I know that I'll be smiling   With my baby by and by
