<P> Preston first met the Beatles as a 16 - year - old in 1962, while part of Little Richard's touring band, when their manager Brian Epstein organized a Liverpool show, at which the Beatles opened . The Washington Post explained their subsequent meeting: </P> <P> They'd hook up again in 1969, when the Beatles were about to break up while recording the last album they released, Let It Be (they would later record Abbey Road, which was released prior to Let It Be). George Harrison, a friend of Preston, had quit, walked out of the studio and gone to a Ray Charles concert in London, where Preston was playing organ . Harrison brought Preston back to the studio, where his keen musicianship and gregarious personality temporarily calmed the tension . </P> <P> Preston is one of several people referred to as the "Fifth Beatle". At one point during the Get Back sessions, John Lennon proposed the idea of having him join the band (to which Paul McCartney countered that it was difficult enough reaching agreements with four). Preston played with the Beatles for several of the Get Back sessions, some of the material from which would later be culled to make the film Let it Be and its companion album, to which he contributed organ and electric piano . Preston also accompanied the band on electric piano for its rooftop concert, the group's final public appearance . In April 1969, their single "Get Back" was credited to "The Beatles with Billy Preston", the only time such a joint credit had been given on an official Beatles - sanctioned release (as distinct from an unsanctioned reissue of some Hamburg - era recordings on which they were the backing group for Tony Sheridan). The credit was bestowed by the Beatles to reflect the extent of Preston's presence on the track; his electric piano is prominent throughout and he plays an extended solo . Preston also worked, in a more limited role, on the Abbey Road album, contributing organ to the tracks "I Want You (She's So Heavy)" and "Something". </P> <P> In 1978, he appeared as Sgt . Pepper in Robert Stigwood's film Sgt . Pepper's Lonely Hearts Club Band, which was based on the Beatles' album of the same name, and sang "Get Back" as the penultimate song . </P>
