Paul McCartney and John Lennon had a knack for finishing each other's songs. They collaborated by lending ideas for verses, choruses and middle eights many times over the course of their partnership. 1967’s “A Day in the Life” is one of the most prominent examples of McCartney and Lennon’s collaboration. What started as a Lennon song, once worked on with McCartney, became a truly collaborative piece—and a standout in The Beatles’ catalog.

“McCartney: A Life in Lyrics” is a co-production between iHeart Media, MPL and Pushkin Industries.
