Ringo Starr joins The Beatles

The Beatles asked Richard Starkey, known as Ringo Starr, to join the band; Starr was the drummer for Rory Storm and the Hurricanes, and had performed occasionally with The Beatles in Hamburg. Starr played on The Beatles' second EMI recording session on 4 September 1962, but Martin hired session drummer Andy White for their next session on 11 September. White's only released performances were recordings of "Love Me Do" and "P.S. I Love You", found on The Beatles' first album.
