John Winston Ono Lennon MBE (born John Winston Lennon, 9 October 1940 – 8 December 1980) was an English singer, songwriter and peace activist who gained worldwide fame as the founder, co-lead vocalist, and rhythm guitarist of the Beatles. His songwriting partnership with Paul McCartney remains the most successful in history. In 1969, he started the Plastic Ono Band with his second wife, Yoko Ono. After the Beatles disbanded in 1970, Lennon continued as a solo artist.
Born in Liverpool, Lennon became involved in the skiffle craze as a teenager. In 1957, he formed his first band, the Quarrymen, which evolved into the Beatles in 1960. He was initially the group's de facto leader, a role gradually ceded to McCartney. Starting in 1967, Lennon's lyrics began to espouse a pacifist message, and some of his songs were soon adopted as anthems by the anti-war movement and the larger counterculture. From 1968 to 1972, he produced more than a dozen records with Ono, including a trilogy of avant-garde albums, his first solo LP John Lennon/Plastic Ono Band, and the international top 10 singles "Give Peace a Chance", "Instant Karma!", "Imagine" and "Happy Xmas (War Is Over)"...
