Paul Oliver in his 'Songsters and Saints' Cambridge Uni Press p105 gives the following as another widely collected stanza [Hearne, Odum & Johnson, Talley, White]:

Nigger and the white man playing seven-up
Nigger won the money scared to pick it up
Nigger made the motion, the white man fell
Nigger grab the money and he run like hell

Also from Odum:

Niggers plant the cotton
Niggers pick it up
White man pockets money
Niggers does without

--Stewie.
