Still fresh from the breakup of The Beatles, John Lennon got to work on music that would become the Imagine album. As he worked on the record through 1971, a film crew documented the process, resulting in a theatrical released the following year. In it, we see Lennon and Yoko Ono at work and guest appearances by everyone from Andy Warhol to Fred Astaire.
The film has now been restored frame-by-frame and is set for theatres on September 17. This new version features 15 minutes of never-before-seen footage recording “How Do You Sleep,” Lennon’s infamous shot at Paul McCartney.
There’s also a 320-page book on the making of the album coming October 9, the day on which John would have turned 78.
Here’s a trailer for the new version.
