The Beatles were asked to come up with a song containing a simple message to be understood by all nationalities. "It was an inspired song and they really wanted to give the world a message," said Brian Epstein. "The nice thing about it is that it cannot be misinterpreted. It is a clear message saying that love is everything." According to journalist Jade Wright, "Lennon was fascinated by the power of slogans to unite people and never afraid to create art out of propaganda. When asked in 1971 whether songs like "Give Peace a Chance" and "Power to the People" were propaganda songs, he answered: 'Sure. So was All You Need Is Love. I'm a revolutionary artist. My art is dedicated to change.
The day before the Our World broadcast, The Beatles decided that the song should be their next single. Released in the UK on 7 July 1967, it went straight to number one and remained there for three weeks. It was similarly successful in the United States after its release on 17 July, reaching number one for a week. It was also included on the American LP version of Magical Mystery Tour in November.
