In the years following the 1960s, Beatles fans around the world were twice-stunned: in 1970, when their beloved group disbanded, and ten years later when the murder of John Lennon ended a decade of hope that somehow the Fab Four would reunite. Between those milestones were astounding highs and unfathomable lows. George Harrison?s 1971 benefit for the suffering of Bangladesh showed the world the possibilities of rock?s altruism, while Lennon asked the world to ?imagine? universal peace before sitting out hald the decade to raise his son. Ringo Starr, the most overlooked Beatle, carved himself a surprising niche in film before launching a string of hit singles. And Paul McCartney, widely seen as the instigator of the breakup, became one of rock?s most beloved performers, racking up record-breaking smashes that climaxed with a triumphant world tour in 1976.
