"A Day in the Life" is a song by The Beatles, the final track on the group's 1967 album Sgt. Pepper's Lonely Hearts Club Band. Credited to Lennon/McCartney, the song comprises distinct segments written independently by John Lennon and Paul McCartney, with orchestral additions. While Lennon’s lyrics were inspired by contemporary newspaper articles, McCartney’s were reminiscent of his youth. The decisions to link sections of the song with orchestral crescendos and to end the song with a sustained piano chord were made only after the rest of the song had been recorded. - Source: Wikipedia
