Professor Dick Flacks writes of the next broadcast of KCSB’s “Culture of Protest” (Thursday, August 28, 6-7pm): “We mark the 45th anniversary of the Great March on Washington for jobs and freedom. In addition to ‘I have a dream,’ you’ll hear a variety of other voices reflecting the lost memory that the March was the result of a diverse coalition of leadership, and that King’s was one of voice of many. And snippets of music by Joan Baez, Bob Dylan, Marian Anderson, Odetta, and Peter Paul and Mary will break through. I am sure Obama will wait to deliver his speech until our program ends.”
