Paul wrote Another Girl in early February of 1965 while vacationing on Hammamet, a Tunisian resort island. The lyrics indicate that McCartney's troubles in his relationship with Jane Asher were worsening. In the recording for the Help! album, Paul not only sings lead, but plays a guitar solo, something new. Another Girl starts with a chorus of all voices, then a verse in the blues-swing style McCartney liked very much. The bridge shifts key from A to C -- an innovation in pop music, but employed twice by the Beatles in the album Help!. (The other instance was You're Going to Lose That Girl.) The backup harmonies are unusually close and intricate for Beatles songs up to this time (usually they were open fifths), but this song gives us a hint of more to come later on.
