«A Day in the Life» is a song by the English band The Beatles and the final track on their 1967 album Sgt. Pepper's Lonely Hearts Club Band. Credited to Lennon–McCartney, the song features separate renditions that were written by band members John Lennon and Paul McCartney separately, with additional orchestral contributions, making this one of the last times they performed a song together as they did in their early years.
