The Beatles’ psychedelic masterwork Sgt Pepper’s Lonely Hearts Club Band has been named the most popular British album in history.

The Official Charts Company said Saturday that the band’s 1967 classic is Britain’s favorite album based on physical sales, downloads and streams in the U.K.

The album found the Beatles at their most experimental and inventive and includes favorites like With a Little Help from My Friends and A Day in the Life. The band by then had stopped touring and was focusing its effort on studio work under the guidance of producer George Martin. The album came ahead of Adele’s 21, which finished second, and the 1995 Oasis album.
