Lyrics:

Bye bye baby,
remember you're my baby
When they give you the eye.
Although I know that you care,
won't you write and declare
That though on the loose,
you are still on the square.
I'll be gloomy,
but send that rainbow to me,
Then my shadows will fly
Though you'll be gone for a while,
I know that I'll be smiling with my baby,
by and by.
(Bye, bye baby, so long!)
Bye bye baby (just you remember that you're my baby when.)
When they give you the eye.
(And although we know that you care,
you just write and declare)
That though on the loose,
you are still on the square.
I'll be gloomy (gloomy),
but send that rainbow to me.
(Then the shadows will fly)
Though you'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 (bye, bye baby)
