One of the biggest musical acts in history, The Beatles were John Lennon (guitar), George Harrison (guitar), Paul McCartney (bass) and Ringo Starr (drums). Lennon and McCartney began playing together in The Quarrymen in 1957; Harrison joined later that year. Before they became The Beatles, they were also Johnny and the Moondogs and The Silver Beatles, joined at times by bandmates including bassist Stuart Sutcliffe (23 June 1940 - 10 April 1962) and drummer Pete Best (b. 24 November 1941); Best was replaced by Ringo to form the final foursome. The early Beatles performed shows in Hamburg, Germany and Liverpool, England, playing covers of early American rock and roll plus original songs by Lennon and McCartney. With hits like `Love Me Do`, `She Loves You` and movies `A Hard Day`s Night` (1964) and `Help!` (1965) Beatlemania was boosted with a worldwide celebrity status. 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.
