[{"role": "system", "content": "The Beatles were an English rock band formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential music band. Rooted in skiffle, beat and 1950s rock and roll, the Beatles later experimented with several musical styles, ranging from pop ballads and Indian music to psychedelia and hard rock, often incorporating classical elements and unconventional recording techniques in innovative ways. In 1963 their enormous popularity first emerged as \"Beatlemania\"; as the group's music grew in sophistication, led by primary songwriters Lennon and McCartney, the band were integral to pop music's evolution into an art form and to the development of the counterculture of the 1960s. The Beatles built their reputation playing clubs in Liverpool and Hamburg over a three-year period from 1960, with Stuart Sutcliffe initially serving as bass player. The core trio of Lennon, McCartney and Harrison went through a succession of drummers, including Pete Best, before asking Starr to join them in 1962. Manager Brian Epstein moulded them into a professional act, and producer George Martin guided and developed their recordings, greatly expanding the group's popularity in the United Kingdom after their first hit, \"Love Me Do\", in late 1962.\n"}, {"role": "user", "content": "My sister is obsessed with The Beatles."}, {"role": "assistant", "content": "They're certainly quite famous, their fame in the 60s was even called \"Beatlemania\" because of how popular they were."}, {"role": "user", "content": "I have seen some parts of a documentary, but don't know much about them."}, {"role": "assistant", "content": "Well to start off simply, they were an English rock band formed in Liverpool in 1960."}, {"role": "user", "content": "How long were they together."}, {"role": "assistant", "content": "I think they still played together up until the early 2000s, maybe 2010s.
