Question
Who wrote Let's go hand in hand not one before another?
Answer
McCartney and Lennon did not have any particular inspiration for the song, unlike some of their later hits such as "Yesterday", "Hey Jude" and "Let It Be". Instead, they had received specific instructions from manager Brian Epstein to write a song with the American market in mind. The song was also recorded in German as "Komm, Gib Mir Deine Hand" ("Come, give me your hand"), one of the only two times The Beatles recorded a song entirely in a language other than English (the other being "She Loves You").
