In keeping with the Beatles' usual philosophy that tracks released on a single should not appear on new albums, both "Strawberry Fields Forever" and "Penny Lane" were left off "Sgt. Pepper's Lonely Hearts Club Band". Martin later stated that this was an approach that he had encouraged, and it was a "dreadful mistake". The Beatles were displeased that Capitol then included the two songs, along with the band's other non-album singles tracks from 1967, on the "Magical Mystery Tour" LP, which the company released as a full-length album, in contrast to the six-track double EP released in the UK and many other countries.
