1966 – Sixty years ago, the Beatles perform their last concert before paying fans at Candlestick Park in San Francisco. he Beatles were an English rock band formed in Liverpool in 1960. The band comprised John Lennon, Paul McCartney, George Harrison and Ringo Starr. They are regarded as the most influential band in popular music and were integral to the development of 1960s counterculture and the recognition of popular music as an art form. Rooted in skiffle, beat and 1950s rock 'n' roll, their sound incorporated elements of classical music and traditional pop in innovative ways. They also explored styles ranging from folk and Indian music to psychedelia and hard rock. As pioneers in recording, songwriting and artistic presentation, the Beatles revolutionized many aspects of the music industry and were often publicized as leaders of the era's youth and sociocultural movements. The Beatles' first visit to the US in 1964 took place when the nation was still mourning the assassination of President John F. Kennedy the previous November. Commentators often suggest that for many, particularly the young, the Beatles' performances reignited the sense of excitement and possibility that had momentarily faded in the wake of the assassination and helped pave the way for the revolutionary social changes to come later in the decade. Their hairstyle, unusually long for the era and mocked by many adults, became an emblem of rebellion to the burgeoning youth culture. During the 1964 US tour, the group were confronted with racial segregation in the country at the time. When informed that the venue for their 11 September concert, the Gator Bowl in Jacksonville, Florida, was segregated, the Beatles said they would refuse to perform unless the audience was integrated. Lennon stated: "We never play to segregated audiences and we aren't going to start now ... I'd sooner lose our appearance money." City officials relented and agreed to allow an integrated show. The group also cancelled their reservations at the whites-only Hotel George Washington in Jacksonville. For their subsequent US tours in 1965 and 1966, the Beatles included clauses in contracts stipulating that shows be integrated.
