Jim Kweskin and the Jug Band did it. Evidently they got it from the singing of Uncle Dave Macon. His version follows:

14. I'VE GOT THE MOURNING BLUES Vo 5095

Been in business and I been in love.
I used to fly high like a turtledove.
Had the blues many a time,
Just a woman on a poor man's mind.

CHO: I got the mourning blues, oh, so bad!
Honey, come and kiss me. They're the worst I've ever had.

Ashes to ashes and it’s dust to dust,
Show me a woman that a man can trust.
Nickel's worth of grease and a dime's worth of lard,
I would buy them all but the times is so hard. CHO.

There ain't no use of me a-working so hard,
For I got a woman in the white folks’ yard.
She brings me meat and she brings me pie.
Me eats some of everything the white folks buy. CHO.

She brings me chicken and she brings me cake.
You just ought to see me lick that plate.
A big honey biscuit and a mutton chop
Will make a nigger's lips go flippy-flop. CHO.

Lassus a fellow right over there,
He's got blue eyes and he's got black hair.
Talking to his sweetheart, she looks so neat,
She calls him honey, and he calls her sweet. CHO.

There stands a feller right over yonder,
He looks just like he wants to ponder.
Look at that hair all around his mouth,
Like he swallered a mule and left the tail a-hanging out. CHO.
