The Beatles

Considered the most influential British pop band ever in the modern history of music, the Beatles were once nothing more than four young boys who came from the noth-west coast of England. 
Their professional musical career started in local clubs in 1960, like the now legendary Cavern Club in Liverpool. Then they got an offer to go to Hamburg, where bands were said to earn up to 15£ a week.
When they got back to England, they soon caught the attention of Brian Epstein, a businessman who was to be their manager till 1967, when he committed suicide. They started to have their first hits in UK in 1962 and in 1964 they became big in America. 
The Beatles lasted ten years together, till 1970, when they broke up because of personal differences.
