"Birthday" is a song written by Lennon-McCartney and performed by the Beatles on their double album The Beatles (commonly known as The White Album). It is the opening track on the third side of the LP (or the second disc in CD versions of the record). The song is an example of the Beatles' return to more traditional rock and roll form, although their music had increased in complexity and it had developed more of its own characteristic style by this point. McCartney and Ringo Starr performed it for Starr's 70th birthday at Radio City Music Hall on 7 July 2010.
