The release of Sgt. Pepper’s Lonely Hearts Club Band is considered not only a milestone in terms of The Beatles discography, but also in 20^th century pop music.

Three fans and admirers of The Beatles talk to Rulo about the album that revolutionised music history. With the musician and writer Joselo, the novelist and screenwriter Hanif Kureishi, and the academic and writer Carmen Pardo.
