John Lennon (1940-80), co-founder of The Beatles, the most commercially successful band in the history of popular music, often served as the band’s wit and social conscience. The Beatles would go on to dramatically change popular music in the 20th century, as well as being a major influence in the arts, pop culture and the counter-cultural revolution. After the group disintegrated in 1970, Lennon pursued a solo career with wife Yoko Ono, focusing on the anti-war movement through music and works of art, in both still and “living” media. It was during this time that his hit song “Imagine” became his legacy to the peace movement. Despite living under the constant threat of deportation from the United States, he continued to be an outspoken political activist. Tragically, he was on the verge of a full-fledged come-back with the album “Milk and Honey” at the time of his murder. He was only 40 years old.
