The E-diminished (E-) can be replaced by an A7 if you wish.
Doc Watson does an excellent version of this.

Let it rain, let it pour
Let it rain a whole lot more, cause
I got them deep river blues,
Let the rain drive right on
Let the waves sweep along, cause
I got them deep river blues.
My old gal's a good old pal,
And she looks like a water fowl, when
I get them deep river blues,
Ain't no one to cry for me,
And the fish all go out on a spree when
I get them deep river blues.
Give me back my old boat
I'm gonna sail if she'll float, cause
I got them deep river blues,
I'm goin' back to Mussel Shoals,
Times are better there I'm told, cause
I got them deep river blues.
Let it rain, let it pour
Let it rain a whole lot more, cause
I got them deep river blues,
Let the rain drive right on
Let the waves sweep along, cause
I got them deep river blues.
If my boat sinks with me
I'll go down, don't you see, cause
I got them deep river blues,
Now I'm gonna say good-bye
'N if I sink, just let me die, cause
I got them deep river blues.
Let it rain, let it pour
Let it rain a whole lot more, cause
I got them deep river blues,
Let the rain drive right on
Let the waves sweep along, cause
I got them deep river blues.
