"All You Need Is Love" is a song by the English rock band the Beatles that was released as a non-album single in July 1967. It was written by John Lennon and credited to the Lennon–McCartney partnership. 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.

John Winston Ono Lennon was an English singer, songwriter and musician. He gained worldwide fame as the founder, co-songwriter, co-lead vocalist and rhythm guitarist of the Beatles. His work included music, writing, drawings and film. His songwriting partnership with Paul McCartney remains the most successful in history.
