Someone recorded a semi-heavy metal version of "You're the One That I Want," the semi-beloved 1978 John Travolta/Olivia Newton-John duet from the film Grease.
They even made a heavily choreographed music video to go with it. You can check it out below.
The band, which is either called Tragedy or Tragedy: All Metal Tribute to the Bee Gees & Beyond (we prefer the latter because we like ridiculous things) has indeed pulled off a spot-on hair-metal spoof of the song, complete with a locker-room scene that takes place at Our Lady of Perpetual Decimation High School.
There's even a reference to Nirvana's "Smells Like Teen Spirit" music video for some reason, plus a Black Sabbath riff or two. By the way, "Tragedy" is the name of a Bee Gees song.
