Universal Music GorupLooks like the YouTube video that purported to reveal all the details of the 50th anniversary edition of the Beatles’ Sgt. Pepper’s Lonely Hearts Club Band was accurate. A slew of album packages marking the anniversary are coming out next month.

“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,” says Paul McCartney in an introduction he wrote for the anniversary edition.

Sgt. Pepper seemed to capture the mood of that year, and it also allowed a lot of other people to kick off from there and to really go for it,” Ringo Starr says in a statement included in the edition’s book.

All the packages, which arrive May 26, will include a new stereo mix of the album by Giles Martin, son of the late Sir George Martin. The mix was sourced directly from the original four-track session tapes. The album has also been expanded with extra tracks from the album sessions, including 34 previously unreleased recordings.

Here’s a rundown of the packages:
