"I Wanna Be Your Man" is a Lennon–McCartney-penned song first recorded and released as a single by the Rolling Stones, and then recorded by the Beatles for their second studio album With the Beatles. The song was primarily written by Paul McCartney, and finished by McCartney with John Lennon in the corner of a Richmond, London club while Mick Jagger and Keith Richards were talking.

Lennon–McCartney was the songwriting partnership between English musicians John Lennon (1940–1980) and Paul McCartney of the Beatles. It is widely considered one of the greatest, best known and most successful musical collaborations ever by records sold, with the Beatles selling over 600 million records worldwide as of 2004. Between 5 October 1962 and 8 May 1970, the partnership published approximately 180 jointly credited songs, of which the vast majority were recorded by the Beatles, forming the bulk of their catalogue.
