There’s an old man called the Mississippi

    6        -5      5    5     6   -5     5    4    -4

That’s the old man that I’d like to be

     5        -4      4   4    5  -4       4          4    -4   -5

What does he care if the world’s got troubles

     5        -4     4    4    5 -4       4        -4       4

What does he care if the world ain’t free

 -2   -2   3  4   3  -2   -2   3  4 

Ol' Man River, dat Ol' Man Riv-er 

-4      5       5        -4        4      -4     5       6    -6    6 

He must know somethin’ but don't say nothin' 

 -6   6         6      5   -4   5       6       6   5  -4    5    4

He just keeps rollin', he keeps on rollin’ along

  -2    -2       -2    3  4   3   -2      -2      3  4

He don't plant 'taters, he don't plant cotton 

-4        5        6      -6          6    -6    7      7   -7   -6

And them that plants them is soon forgotten 

  -7    6    6     5   -4      5    6        6     5  -4    5    4

But Ol' Man Riv-er, he just keeps rollin' along

  -3   -2   3        4       -3      -2       3

You and me, we sweat and strain 

-3  -3  -2   3  3       4     -3         -2        3

Body all achin' and racked with pain 

  -2      2      -2/      -2     2     -2/   

Tote that barge! Lift that bale!

  3    -2   -2   2   2   -2/       3     3       -2     2    -1

You gets a little drunk, and you lands in jail

-2   -2   3  4      3   -2    -2   3   4

I   get weary and sick of tryin' 

-4       5     6   -6   6   -6        7       7   -8   7

I’m  tired of living and scared of dying

 -8     8     8    -8   7  -8    8      8      -8    7    -8    7

But Ol' Man River he just keeps rollin' along
