That Bukka White sounds like a good song. I'll have to find it and give it a listen. But it's not the song I was talking about. The song I'm talking about is:

DIVING DUCK BLUES
(Sleepy John Estes)

Now if the river was whiskey,
And I was a diving duck,
Now if the river was whiskey,
And I was a diving duck,
I would dive on the bottom,
Never would come up.

Don't never take
A married woman to be your friend.
Don't never take
A married woman to be your friend.
She will get all your money,
And give it to her other man.

Now a married woman
Always been my friend.
Now a married woman
Always been my friend.
Now a married woman
Gonna carry me to my grave.

Now ain't it hard
To love someone thats dead(??)?
Now ain't it hard
To love someone thats dead(??)?
You can't get her when you wanna,
Have to use her when you can.

Now the sun gonna shine
On my backdoor someday.
Now the sun gonna shine
On my backdoor someday.
Now the wind gonna rise
Gonna blow my blues away.

Now I went to the railroad,
Looked up at the sun.
Now I went to the railroad,
Looked up at the sun.
If the train don't hurry,
Gonna be some walking done.

I'm not sure about that word in the 2nd verse - it sounds like "dead", but "wed" would seem to make more sense...
Sleepy John Estes recorded this in 1929. The recording also features wonderful mandolin by Yank Rachell.
I'm listening to it on "I Ain't Gonna Be Worried No More" .
