"I'm the Greatest" is a song written by English musician John Lennon that was released as the opening track of the 1973 album Ringo by Ringo Starr. With Starr, Lennon and George Harrison appearing on the track, it marks the only time that three former Beatles recorded together between the band's break-up in 1970 and Lennon's death in 1980. Lennon wrote the song in December 1970 as a wry comment on his rise to fame, and later tailored the composition for Starr to sing. Named after one of Muhammad Ali's catchphrases, the song partly evokes the stage-show concept of the Beatles' 1967 album Sgt. Pepper's Lonely Hearts Club Band.
