As part of the film contract, United Artists acquired album rights for the American market. The company released a soundtrack album on 26 June 1964 with eight Beatles songs and four instrumentals. "I Should Have Known Better" was performed in the film, and it appears on the soundtrack. Capitol Records released Something New a month later with songs from the UK version of A Hard Day's Night that were not used in the film. The songs were also later released by Capitol on the Hey Jude compilation album in 1970. Continental Europe "I Should Have Known Better" was released as a single in a number of continental European countries, including Norway, where it reached number one, Italy where it spent a week at number 15, West Germany, where it reached number six, and Sweden, where it topped the Kvällstoppen Chart for four weeks. Personnel John Lennon – double-tracked vocal, acoustic rhythm guitar, harmonica Paul McCartney – bass guitar George Harrison – twelve-string lead guitar Ringo Starr – drums Personnel per Ian MacDonald On film The song is performed in the train compartment scene of A Hard Day's Night. It was in fact filmed in a van, with crew members rocking the vehicle to simulate the action of a train in motion. Paul McCartney is seen lip-syncing in the song, both in the train scene and in the live performance at the end of the film, despite not singing in the actual recording.
