The song was written by band members Zac Barnett, Dave Rublin, Matt Sanchez, and James Adam Shelley, along with producers Aaron Accetta and Shep Goodman. "Best Day of My Life" was originally recorded for release as a single by Mercury Records and Island Records on March 19, 2013, and later appeared as the second track on the band's third extended play American Authors (2013) and the third track on their debut studio album, Oh, What a Life (2014).
A Day in the Life "A Day in the Life" is a song by the English rock band the Beatles that was released as the final track of their 1967 album Sgt. Pepper's Lonely Hearts Club Band. Credited to Lennon–McCartney, the verses were written mainly by John Lennon, with Paul McCartney primarily contributing the song's middle section. Lennon's lyrics were inspired by contemporary newspaper articles, including a report on the death of Guinness heir Tara Browne. The recording includes two passages of orchestral glissandos that were partly improvised in the avant-garde style. As with the sustained piano chord that closes the song, the orchestral passages were added after the Beatles had recorded the main rhythm track.
