"Birthday" is a song written by John Lennon and Paul 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). This song is a prime 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.
