We are going to take a look at the last fifty years of world history — framed by the history of the Pacifica network, the nation’s first listener-supported, community-based radio network founded by pacifist and artist Lewis Hill in 1949. This audio tour, produced by WBAI programmer Peter Bochan, brings the voices of some of the most important (and some of the least heard) social justice activists of the fifty years to the airwaves. We’ll hear from Harry Truman, William Mandel, Lewis Hill, Samori Marksman, Verna Avery Brown, Alan Watts, Gore Vidal, William Kunstler, Paul Robeson, Lawrence Ferlinghetti, Joan Baez, John F Kennedy, Che Guevara, Rosa Parks, Martin Luther King, George McGovern, Bob Fass, Eldridge Cleaver, Richard Nixon, Mario Savio, Bella Abzug, Cesar Chavez, Nelson Mandela, Jean-Bertrand Aristide, Oliver North, Saddam Hussein, Phil Gramm, Bill Clinton , Fidel Castro, and Mumia Abu-Jamal.
