Paul McCartney [SEP] Introduction
McCartney began his career as a member of the Quarrymen in 1957, which evolved into the Beatles in 1960. Starting with the 1967 album "Sgt. Pepper's Lonely Hearts Club Band", he gradually became the Beatles' "de facto" leader, providing the creative impetus for most of their music and film projects. His Beatles songs "And I Love Her" (1964), "Yesterday" (1965), "Eleanor Rigby" (1966) and "Blackbird" (1968) rank among the most covered songs in history. In 1970, McCartney debuted as a solo artist with the album "McCartney". Throughout the 1970s, he led Wings, one of the most successful bands of the decade, with more than a dozen international top 10 singles and albums.
