In this new PBS special, Peter, Paul And Mary recall, along with Mentors Pete Seeger and Ronnie Gilbert, the beginnings of the cultural revolution of the 1960s, when music became a unifying force amidst the hopeful, idealistic, and sometimes turbulent movements of social change. Carry It On: A Musical Legacy features rare archival performances of songs which energized the spirit of the nation`s cultural and political renaissance. They include "Blowin` In The Wind" from the 1963 march on Washington, and "The Times They Are A Changin`" recorded at the Newport Folk Festival. These and other historic moments are woven together with songs and clips from the trio`s four highly acclaimed PBS specials, as well as intimate rehearsal renditions of songs from their 2004 album In These Times.
