The Beatles plan to celebrate the 50th anniversary of their legendary “Sgt. Pepper’s Lonely Hearts Club Band” in style, with a massive reissue that includes previously unreleased songs from the album’s recording sessions.

“It’s crazy to think that 50 years later we are looking back on this project with such fondness and a little bit of amazement at how four guys, a great producer and his engineers could make such a lasting piece of art,” Paul McCartney said in a statement.

The album will be reissued in a variety of formats on May 26, just days before its golden anniversary. The biggest of the packages is a $150, six-disc “super deluxe” edition, which includes new stereo, surround sound and mono mixes of the original album, two CDs of additional songs from the recording sessions, and a DVD with restored videos of “Strawberry Fields Forever,” “Penny Lane” and “A Day in the Life,” as well as a documentary of the making of the album.
