Paul McCartney and John Lennon are possibly the most successful songwriting duo ever. They wrote many hits together, and it’s hard to imagine how many more they could have written if The Beatles stayed together. They started writing together at a young age, and McCartney remembered the first song he called a “Lennon-McCartney original.”
Paul McCartney declared ‘Just Fun’ as an early ‘Lennon-McCartney original’

Lennon and McCartney first met while in Liverpool and had an instant connection. They bonded over their shared love of rock n’ roll music, which was hard to find as rock music was just starting to become popular in the U.K. Before Lennon and McCartney formed The Beatles, the pair wrote songs together while in The Quarrymen.
