The new documentary Disturbing the Peace tells the riveting story of Combatants for Peace, a group of former enemies — Israeli soldiers and Palestinian fighters, many of whom served years in prison — who are now committed to non-violent peace activism.

The film won the first-ever Ebert Humanitarian Award, given to films that exemplify humanity and empathy.

The filmmakers chose my song "I Shall Be Free" to play over the closing credits. An allegorical tale of a "soldier of love," the song served as a touchstone for the directors as they shot and edited the film.

I'm honored to be a part of it. The film is a vital, heartbreaking, triumphant portrait of the long, hard path of the peaceful warrior. It will touch and inspire the hearts and actions of many, many people in the years to come.
