It is well known that the Beatles had stopped performing live by the late 1960s.
By 1966, the Fab Four were working hard on what would be their eighth album - but they wanted to majorly switch it up. Instead of just stringing together another batch of singles into an album, the band's primary songwriters, Paul McCartney and John Lennon, wrote a concept album: Sgt Pepper's Lonely Hearts Club Band.
The album has become one of The Beatles' biggest and best-known albums of all time. Not only did it include such iconic hits as its title track and Lucy in the Sky with Diamonds, but it also housed With a Little Help from My Friends and A Day in the Life.
