Nobody ever plays on Beatles records."

It was written by George Harrison, the band\'s lead guitarist. The song serves as a comment on the disharmony within the Beatles following their return from studying Transcendental Meditation in India in early 1968. This lack of camaraderie was reflected in the band\'s initial apathy towards the composition, which Harrison countered by inviting his friend and occasional collaborator, Eric Clapton, to contribute to the recording. Clapton overdubbed a lead guitar part, although he was not formally credited for his contribution.']}}]}]
