The lyrics of Paul McCartney and John Lennon were once inseparable. The formidable songwriting duo co-wrote most of The Beatles hits under the moniker Lennon-McCartney.

Over the years, the two made various claims on who penned certain iconic lyrics from those tracks. Then the two had full creative freedom for their solo careers, after The Beatles split in 1970. John Lennon created albums with his wife Yoko and her Plastic Ono Band, while McCartney formed Wings which also featured his wife Linda McCartney.

With 31 solo albums between them, there are a lot of standout lyrics across the years (for better or for worse).
