N. I. White, in American Negro Folk songs, discusses "Run, Nigger, Run and gives fragmants of several versions. The earliest he found is in White's "Serenaders' Song Book" copyright 1851.

De sun am set- dis nigger am free,
De colored gals he goes to see.
I heard a voice cry, "Run, dad, fetch you!
Run, nigger, run, or de M. P. 'll catch you!"

Chorus and repeat
Run, nigger, run, de M. P.'ll catch you!
Run, nigger, run tum a du daddle da!
"The other stanzas describe mainly the manner of the running."
The song also appears in "Uncle Remus and His Friends, p. 200.
