"All You Need Is Love" is a song written by John Lennon and Paul McCartney (though largely the work of Lennon) and recorded by The Beatles. It originally appears on the 1967 Beatles album Magical Mystery Tour. It is arguably the most significant song ever performed by the Beatles.
The song includes some sections from other songs, amongst them French national anthem "La Marseillaise", Bach's "Brandenburg Concerto", Bach's "2-part invention #8 in F major", "Greensleeves", "In The Mood", and Beatles songs "She Loves You" and (momentarily) "Yesterday". As a whole the song features contrasting verse-chorus form.
AYNIL was commissioned by the BBC and was performed by The Beatles as part of the UK contribution to Our World, the first global television programme, watched by 350 million people via satellite across the planet on 25 June 1967. This performance appears in The Beatles Anthology documentary series, partly colorized using colour stills of the performance as a reference.
The song was literally recorded live as it was being broadcast, having been written by John Lennon and Paul McCartney with a brief from the BBC to 'keep it simple so that viewers across the globe will understand', though part of the track was recorded on tape eleven days earlier.
This song was also aired on the final episode of the British SF/Espionage series The Prisoner.
