Standard 1CD 50th Anniversary Edition 'Sgt. Pepper's Lonely Hearts Club Band' was the eighth studio album by the Beatles. First released on 1 June 1967, it was an immediate commercial and critical success, spending 27 weeks at the top of the albums chart in the United Kingdom and 15 weeks at number one in the United States. The album is newly mixed by Giles Martin and Sam Okell in stereo, sourced directly from the four-track masters and guided by the original, Beatles-preferred mono mix produced by his father, George Martin.
