"I Should Have Known Better" is a song by English rock band the Beatles composed by John Lennon (credited to Lennon–McCartney), and originally issued on A Hard Day's Night, their soundtrack for the film of the same name released on 10 July 1964. "I Should Have Known Better" was also issued as the B-side of the US single "A Hard Day's Night" released on 13 July. An orchestrated version of the song conducted by George Martin appears on the North American version of the album, A Hard Day's Night Original Motion Picture Soundtrack. Origin "I Should Have Known Better" was one of several songs written and recorded specifically for the Beatles' debut movie, "A Hard Day's Night". The harmonica-driven arrangement by the group was similar to Frank Ifield's recording of "The Wayward Wind", a hit on the UK Singles Chart in March 1963. The Beatles were fans of Ifield and his music, and recorded his rendition of "I Remember You" in their Hamburg stage act in 1962. Recording The first recording session for the song was on 25 February 1964 at EMI Studios when three takes were attempted, but only one was complete. Take two was aborted when Lennon broke into hysterics over his harmonica playing. The song was re-recorded the next day after making some changes to the arrangement. Lennon's harmonica playing opens the track, the last occasion the Beatles were to feature this instrument on an intro ("I'm a Loser", recorded 14 August 1964 has a harmonica solo). The song's middle sixteen section features George Harrison's new Rickenbacker 360/12 12-string guitar. The mono and stereo versions have slightly different harmonica introductions. In the stereo version, the harmonica drops out briefly. Also, a noticeably clumsy and audible tape edit is heard during the second chorus between "You're gonna say you love me too, oh," and "And when I ask you to be mine."
