All You Need Is Love was written by John Lennon and released by The Beatles in 1967. It was first performed live on Our World, the first global satellite television broadcast, reaching an international audience at once. Released as a standalone single shortly afterwards, its simple refrain and message of unity made it an anthem of the Summer of Love. Online, the chorus is widely reused as a shorthand for affection and optimism, appearing in romantic edits, tributes, and wholesome memes where an instantly familiar, positive hook is needed.
