The Beatles - all you need is love, 1967

"The song was Britain's contribution to Our World, the first live global television link, for which the band were filmed performing it at EMI Studios in London on 25 June. The programme was broadcast via satellite and seen by an audience of over 400 million in 25 countries. Lennon's lyrics were deliberately simplistic, to allow for the show's international audience, and captured the utopian ideals associated with the Summer of Love. The single topped sales charts in Britain, the United States and many other countries, and became an anthem for the counterculture's embrace of flower power philosophy. Our World coincided with the height of the Beatles' popularity and influence, following the release of their album Sgt. Pepper's Lonely Hearts Club Band. Rather than perform the song entirely live, the group played to a pre-recorded backing track. With an orchestral arrangement by George Martin, the song begins with a portion of the French national anthem and ends with musical quotations from works such as Glenn Miller's "In the Mood", "Greensleeves", Bach's Invention No. 8 in F major, and the Beatles' 1963 hit "She Loves You".
