My mom sang a version of this, I never thought I'd find it...

I've a dear little wife,
she's the joy of my life,
just three years younger than I.
She's full of enjoyment,
and plenty of life,
sometimes she goes out on a spree.
She leaves me behind,
the baby to mind,
the house in good order to keep.

Chorus:
Hush a la, La coo, La hush-a-bye baby,
Tossing the baby ever so high
Hush a la, La coo, La hush-a-bye baby,
Mama will come bye-and-bye.

One night after rocking the baby to sleep,
I took a short walk on the street,
When to my surprise, I saw with my eyes
My wife and a Soldier six-feet.
At first I was rout,
She passed me and smiled, and said I was taking a peek.
She tickled my chin and said Willy go in, and rock the dear baby to sleep.

Repeat Chorus
