Editors’ Notes A Hard Day's Night was both a soundtrack to the dazzling Richard Lester-directed film and a triumphant album unto itself. It was the first album to contain only music written by John Lennon and Paul McCartney as well as the band's first foray into four-track recording. A Hard Day's Night offers up a multitude of different sounds (bongos, harmonica, double-tracked vocals, cowbells) included on vibrant tracks such as the title tune and “Can't Buy Me Love” as well as thoughtful melodies like "I Should Have Known Better." A Hard Day’s Night is full of youthful optimism, but The Beatles show a remarkable maturity in their songwriting and arranging on tracks like "If I Fell" and "And I Love Her.”
