The songwriting partnership of John Lennon and Paul McCartney, usually referred to as Lennon/McCartney (sometimes McCartney/Lennon), is one of the best-known and most successful musical collaborations of all time. In an agreement reached early in their partnership, the pair agreed to use the shared credit Lennon/McCartney on all songs written alone or in tandem, for The Beatles. Their output constitutes the bulk of The Beatles' catalog.
Lennon, with his cynical edge and knack for introspection, and McCartney, with his storytelling optimism and gift for melody, complemented each other. Lennon and McCartney formed a critically acclaimed and commercially successful partnership writing songs for The Beatles and other artists.
