PEOPLE The Beatles: Sgt. Pepper at 55

Fifty-five years ago, the Beatles introduced Sgt. Pepper’s Lonely Hearts Club Band, now considered one of the greatest rock albums of all time. This special edition explores their Summer of Love masterpiece, with the stories behind the songs, interviews with the band, and a complete who’s who of the crowded-with-pop-culture-icons album cover. It’s hard to believe that all these groundbreaking songs first appeared on just one album: “With a Little Help from My Friends,” “Lucy in the Sky with Diamonds,” “A Day in the Life” and the rest of this classic lineup. Packed with glowing photos of John, Paul, George and Ringo, plus all of the friends who helped them get by, this is the perfect keepsake for Beatles fans everywhere.
