The Beatles' classic Sgt. Pepper's Lonely Hearts Club Band is celebrating its 50th anniversary. That's incredible. And while many of us may know the music front to back, a new previously unreleased version of the opening song has been released.

This version is one of 34 unreleased outtakes that will be included in the new reissue of the album. It's a little more rough around the edges and includes muffled chatter in the studio.
