"Love Me Do" is the debut single by the English rock band the Beatles, backed by "P.S. I Love You". When the single was originally released in the United Kingdom on 5 October 1962, it peaked at number 17. It was released in the United States in 1964 and topped the nation's song chart. Re-released in 1982 as part of EMI's Beatles 20th anniversary, it re-entered the UK charts and peaked at number 4. "Love Me Do" also topped the charts in Australia and New Zealand.
The song was written several years before being recorded, and prior to the existence of the Beatles. It features John Lennon's prominent harmonica playing and duet vocals by him and Paul McCartney. Three recorded versions of the song by the Beatles have been released, each with a different drummer.
