In 1980, David Sheff met Yoko and John when Sheff conducted an in-depth interview with them just months before John’s murder. In the aftermath of the killing, he and Yoko became close as she rebuilt her life, survived threats and betrayals, and went on to create groundbreaking art and music while campaigning for peace and other causes. Sheff shows us Yoko’s nine decades—one of the most unlikely and remarkable lives ever lived. Photo: Bas Bogaerts.
