COCK-A-DOODLE, I'M OFF MY NOODLE (MY BABY'S BACK)
Words & music by by Howard E Johnson, Al Sherman & Charles Tobias, ©1926.

I was blue, broken hearted,
Oh, so blue, when we parted,
Never though my baby'd go away.
Skies were gray; now they're lighter,
And today, things are brighter.
I feel just like shouting, shouting hooray!

Cock-a-doodle! I'm off my noodle; I'm through with wearing a frown.
My baby's back; my baby's back.
Cock-a-doodle! I'm off my noodle, and soon my arms will be 'round
My baby's back, my baby's back.
I've made my mind up, mind up, we were all though before,
But now I'll wind up, wind up, loving her more and more.
Cock-a-doodle! I'm off my noodle; I'm all though dressing in black,
'Cause baby's back; my baby's back.

Cock-a-doodle! I'm off my noodle; I'm simply walking on air.
My baby's back; my baby's back.
Cock-a-doodle! We'll bill and coodle; I've bought a new morris chair
For baby's back, my baby's back.
Oh, how I missed her, missed her, while she was far away!
I longed to kiss her, kiss her, more and more ev'ry day.
Cock-a-doodle! I'm off my noodle; I'm making up for it now.
My baby's back; my baby's back.

Cock-a-doodle! I'm off my noodle; I'm through with wearing a frown.
My baby's back; my baby's back.
Cock-a-doodle! I'll spend a boodle and buy a beautiful gown
For baby's back, my baby's back.
Oh, how I love her, love her, face is so cute and round.
There's so much of her, of her, only three hundred pounds!
And when we go to a movie show, you know, all that people can see
Is baby's back, my baby's back.
