Could it be this song? I've never heard the Louvins do it, however.


Mississippi Delta Blues

With friends around and even pals that I know are true
Still I'm lonely homesick and blue
There's no one who can cheer me when I'm all alone
Longing for my Mississippi home.

Chorus:
   Way down on the delta on the Mississippi shore
   In that muddy water I long to be once more
   When night shadows creep about and the whippoorwill calls
   You can hear old Mammy shout, "Come in here you all."
   Way down on the levee strolling in the pale moon light
   You can see those steamboats and fields of snowy white
   That's a feeling I can't lose muddy water in my shoes
   When I get those Mississippi Delta blues (yodel)

I long to hear the darkies sing them old melodies
Swanee River and Ol' Black Joe
That sweet magnolia perfume floating on the breeze
Way down south is where I long to go.

Chorus
