Kurt Cobain‘s unreleased version of The Beatles‘ “And I Love Her” has appeared online.

The demo recording was discovered by Brett Morgen, director of the recent Cobain documentary, Montage Of Heck, while sifting through Cobain’s extensive audiotape archive.

Rolling Stone reports that while the track will be included in the film’s soundtrack — along with other never-before-heard tracks from Cobain’s archive —this full version has leaked online.

“Nobody in Kurt’s life — not his management, wife, bandmates — had ever heard his Beatles thing,” Morgen told Rolling Stone. “I found it on a random tape.”
