Answer 1

"Can't Help Lovin' Dat Man"  Lyrics

Showboat Soundtrack

Fish got to swim, birds got to fly,

I got to love one man till I die.

Can't help lovin' dat man of mine.

Tell me he's lazy, tell me he's slow,

Tell me I'm crazy, (maybe I know).

Can't help lovin' dat man of mine.

Oh listen sister,

I love my mister man,

And I can't tell you' why

Dere ain't no reason

Why Ishould love dat man,

It mus' be sumpin dat de angels done plan.

Fish got to swim, birds got to fly,

I got to love one man till I die.

Can't help lovin' dat man of mine.

Tell me he's lazy, tell me he's slow,

Tell me I'm crazy, (maybe I know).

Can't help lovin' dat man of mine.

When he goes away,

Dat's a rainy day,

And when he comes back dat day is fine,

De sun will shine!

He kin come home as late as can be,

Home without him ain't no home to me,

Can't help lovin' dat man of mine.

De chimney's smokin'

De roof is leakin' in,

But he don't seem to care.

Dere ain't no reason why I should love dat man.

And why do you love that man?

It mus' be sumpin' dat de angels done plan.

Fish got to swim, While de birds fly,

Birds got to fly, Till the world dies

I got to love My gal loves me;

One man till I die. Dat's why she's

Can't help lovin' True gal of mine.

Dat man of mine. She may be lazy

Tell me he's lazy, and slow as cold

Tell me he's slow, Molasses, I know,

Tell me I'm crazy, Can't help lovin'

(maybe I know). Dat gal of mine.

Can't help lovin' When I goes away

Dat man of mine. Dat's lovin

When he goes away, All de rainy days,

Dat's a rainy day, Dat's loving.

And when he comes back An' when I comes

Dat day is fine, Back' dat day is fine,

De sun will shine!

Yes, sister Yes, sister

He kin come home She kin come home

As late as can be, as late as kin be,

Home without him Home widout her

Ain't no home to me, Ain't no home to me,

Can't help lovin' Can't help lovin'

Dat man of mine. Dat gal of mine.

Answer 2

It is a line from a song titled "Can't Help Lovin' Dat Man" (music by Jerome Kern; lyrics by Oscar Hammerstein II) from their 1927 musical play "Show Boat," adapted from Edna Ferber's novel.

It is from a verse that reads:

"Fish got to swim, birds got to fly,

I got to love one man till I die.

Can't help lovin' dat man of mine."
