John Henry & the Cocaine Blues

Here's a look at American music's ultimate crossover song: John Henry. To African-Americans he was a symbol of racial pride; to unionists, he represented the power of the American worker and union solidarity; to poor whites; he was  personification of rugged Americanism, and to Christians; a Christ-like figure who died for our sins.  And, as a bonus, a look at two versions of one of the oddest songs in blues and folk music, the Cocaine Blues.
