Watch Fmovies. Since her debut at the age of 18, musician, civil rights campaigner and activist Joan Baez has been on stage for over 60 years. For the now 82-year-old, the personal has always been political, and her friendship with Martin Luther King and her pacifism have shaped her commitment. In this biography that opens with her farewell tour, Baez takes stock in an unsparing fashion and confronts sometimes painful memories.
