"All My Loving" is a song by The Beatles, written by Paul McCartney (credited to Lennon/McCartney), from the 1963 album With The Beatles. Though it was not released as a single in the United Kingdom or the United States, it drew considerable radio airplay, prompting EMI to issue it as the title track of an EP.
According to journalist Bill Harry, McCartney wrote the lyrics while shaving, though McCartney told biographer Barry Miles that he wrote them while on a tour bus. He also said, "It was the first song I'd ever written the words first. I never wrote words first, it was always some kind of accompaniment. I've hardly ever done it since either." The lyrics follow the "letter song" model as used on "P.S. I Love You", the B-side of their first single. After arriving at the location of the gig, he wrote the music on a piano backstage.
McCartney originally envisioned it as a country & western song, and George Harrison added a Nashville-style guitar solo. John Lennon's rhythm guitar track uses quickly strummed triplets similar to "Da Doo Ron Ron" by The Crystals, a song that was popular at the time.
