The Beatles’ studio albums contain plenty of small details that can be hard to pick up on. Some of these consist of fascinating and formally innovative composition and recording choices; some are dumb jokes meant to mess with listeners’ dogs. Others, like a voice saying “Fucking hell” deep in the mix of “Hey Jude” are mysteries that fans can spend decades contemplating. Buzzfeed News outlines that last fact fact, probably unknown to plenty of people who don’t think a Beatle is swearing anywhere in “Hey Jude.” The video points out exactly where the curse is—”just before three minutes” in the center channel—and plays it so you can hear it for yourself.
