1963 their song "She Loves You" was the biggest hit in U. K. history. Their personal charm and charisma helped boost "Beatlemania," and their tour of the U.S. in 1964 led to sold-out concerts and mob scenes. Their movies A Hard Day's Night (1964) and Help! (1965) capitalized on their humor and youthful exuberance and were box office successes, and the hit songs kept coming: in 1964 they had five straight number one albums. In the late '60s their songs became more sophisticated and their worldwide celebrity status prompted Lennon to joke "we're bigger than Jesus." By 1970 they were no longer performing in public and were beginning to pursue individual projects. In December of 1970 McCartney brought a lawsuit to dissolve The Beatles as a legal entity, and the group broke up. Their hits are too numerous to mention, and their impact on pop music can't be overstated. In 1980 Lennon was murdered, and in 2001 Harrison died of cancer, but McCartney and Starr continue to have busy solo careers. Answers.com
