In 1963 the United States convulsed with the civil rights movement. Canadian writer Austin Clarke made a documentary for CBC Radio about Harlem and the conditions for the African-Americans who lived there. Rewind features part one of the documentary "Harlem in Revolt."
Last December, Cuba watchers were surprised to learn that President Barack Obama was working secretly to normalize relations between the U.S. and Cuba, after more than 50 years of embargo. Rewind airs a documentary from 1958 just weeks before the Cuban Revolution.
