My favorite version is by Frank Stokes.

Slightly different title but same basic song.

'TAIN'T NOBODY'S BUSINESS IF I DO - Part 2 (Take 2)
As sung by Frank Stokes on "Memphis Rounder: The Complete Victor Recordings in Chronological Order (1928-1929)" (Document Records, DOCD-5013)

I'm goin' stay round in Tennessee
Where the girls round here take a like to me
Though I won't have no other place to go
Now listen at me, baby; be good and kind
You mistreat and leave me all the time
Ain't nobody's business but mine

Ain't nobody's business, baby,
Nobody's business but mine
It ain't nobody's business, honey,
Where in the world I spend my money
Nobody's business but my own

Now listen, baby, you oughta been told me
Fourteen years before you wrote me
So I would 'a' had some other place to go
I laid my head in the corner of the fence
Said crazy 'bout her treatments ever since
It ain't nobody's business but my own

Nobody's business, baby, nobody's business, baby,
Nobody's business but mine
Nobody's business, honey,
Where in the world I find my money
Nobody's business but my own

I'm going back to Memphis, Tennessee
Where the gals round here always stay round me
It ain't nobody's business but mine
I been careful, I stay at home,
I've been troubled 'bout you ever since you've been gone
It ain't nobody's business, baby, but mine

It ain't nobody's business, honey,
Where in the world I spend my money
Nobody's business but mine
Nobody's business, kid,
Where in the world I got my money hid
Said it ain't nobody's business but my own
