Simple is better, after all, “All You Need Is Love”

18 May 1967, the Beatles were selected to represent the UK for the first-ever global-wide satellite broadcast: Our World.
The TV show was the first live international production, which was broadcast on 25 June 1967 via satellite.
The Beatles were asked, for the occasion, to provide a song with a message that could be easily understood by everyone.
The song sprang from the “Summer of Love”, it sums up the feelings that the hippie movement and the Beatles shared in the summer of 1967.
This masterpiece was written by John Lennon (and credited to Lennon–McCartney) on the basis of the BBC’s request to "keep it simple” in order to be easily understood by people all around the world.
What is simpler than a message of pure love?
The Beatles performed the song during the Our World show, watched by over 400 million in 25 countries.
The song fulfilled its aim, it captured the feelings and the common sentiment of the Summer of Love and topped the charts in UK, US and many other countries.
"All You Need Is Love" was later included on the US Magical Mystery Tour album.
