"You're Going to Lose That Girl" is a song by the English rock band the Beatles from their 1965 album and film Help! Credited to the Lennon–McCartney songwriting partnership, the song was mostly written by John Lennon with contributions from Paul McCartney. Composition and recording Credited to the Lennon–McCartney partnership, Walter Everett and Ian MacDonald both refer to the song as Lennon's. In his official biography Paul McCartney: Many Years from Now, Paul McCartney estimates the writing as 60–40 to John Lennon. The song was likely written in January or February 1965. In a 16 January 1965 interview with Ray Coleman for Melody Maker magazine, Lennon explained he had only written "half a song" for the Beatles' next film. From 25 January to 7 February, Lennon and his wife Cynthia vacationed in the Austrian Alps with Beatles producer George Martin and Martin's future wife, Judy Lockhart-Smith. The time off from touring provided Lennon, McCartney and George Harrison time to write new songs, eventually recording 11 new tracks between 15 and 20 February. The Beatles recorded two takes and overdubs of "You're Going to Lose That Girl" during an afternoon session at EMI on 19 February 1965. The next day Martin, assisted by engineers Norman Smith and Ken Scott, mixed the song for mono. On 23 February while the Beatles filmed scenes for Help! in The Bahamas, engineers Smith and Malcolm Davies mixed the song for stereo twice, preferring the second mix over the first. On 30 March the Beatles recorded more overdubs onto the song. An electric piano and Harrison's original guitar solo were erased from the original tape. Everett describes the original guitar solo as "tortured" due to the heavy string gauge on Harrison's brand new Fender Stratocaster. Harrison recorded a new guitar solo, Ringo Starr played bongos and McCartney played piano. On 2 April Martin, assisted by Smith, made another stereo mix of the song using the 30 March overdubs. This stereo mix was included on both the UK and US stereo releases of Help! In the film Help! In the film, the group appears singing this song in the recording studio. In addition to the group's familiar guitar-and-drum setup, there is also footage of Paul McCartney at a piano and Ringo Starr playing the bongos, both miming instruments they had overdubbed onto the recording.
