From John Lennon and Yoko Ono's famous bed-in in 1969 sprung "Give Peace a Chance", the first global peace anthem. This programme revisits that moment and the song with fresh eyes. It features Yoko Ono's longest interview with the media in 25 years and showcases never-before-seen bed-in footage from her private archive. Other people who were there like singer Petula Clark and Life Magazine photographer Gerry Deiter tell their stories for the first time. Pete Seeger makes a special appearance, singing "Give Peace a Chance".
