How long, brethren, how long,
Must my people weep and mourn?
How long, how long, brethren, how long?

So long my people been asleep
White folks plowin' my soul down deep.
How long, how long, brethren how long?
Too long, too long, brethren, too long.

We just miserin' along too long brethren too long.
White folks ain't Jesus, he just a man,
Grabbin' biscuit out of poor nigger's hand.
Too long, too long, brethren too long.
(Gellert 16)

Re the Scottsboro Boys:
Paper come out, done spread the news that
Seven poor childrin moan death house blues.
Seven poor childrin moanin' death house blues.

Seven nappy heads with big shiny eyes
All bound in jail and framed to die
All bound in jail and framed to die ....

Judge and jury all in the stand
Lawd, biggety name for same lynchin band
Lawd biggety name for same lynchin band (Gellert 44)
