I found this on Spotify, on two albums: "Jack Newman (1938)," Document Records DOCD-5351, 1995; and "Coal Man Blues," Suncoast Music, 2015.


COAL MAN BLUES
As recorded by James Hall (vocal?) and Jack Newman (piano?), 1938.

I am a coal man, knocking at your door. (2x)
I can't credit you today until you pay for that you got before.

I furnish you coal, honey, just to cook your meals. (2x)
And when you don't pay me, how do you think I feel?

Now your coal box is empty; what d'you expect for me to do? (2x)
Spend my money for coal and credit it out for you?

Since you are a good little lady, I will treat you nice and kind. (2x)
I will credit you for coal if you haven't got a dime.

I believe I will put the coal bus'ness down. (2x)
When you ladies gets my coal, you tries to dog me aroun'.
