Their main songwriters were Lennon and McCartney. Before The Beatles became popular, they played in clubs in Liverpool and Hamburg over three years between 1960 and 1963, with Stuart Sutcliffe playing bass. They went through many drummers, including Pete Best, before finally asking Ringo Starr to join in 1962. Sutcliffe also quit, meaning Paul McCartney started playing the bass instead. Brian Epstein was their manager and George Martin produced most of their music. Their first single was "Love Me Do", in late 1962. It was a hit and they became popular in the United Kingdom. As they became more popular, the press called the popularity "Beatlemania".
