Yes, by now, most of us have seen Grease, the late '70s film adaptation of the stage production starring John Travolta, Olivia Newton-John and Stockard Channing. It's a film classic, though there are several nitpicky things that are sure to eat away at some viewers. For instance, for a group of guys who are supposed to be badass leather jacket wearing gang members, the T-Birds seem rather tame. That's where Andy Rehfeldt comes in.

Over the years, Rehfeldt has become quite popular via YouTube viewers for taking familiar songs or video clips and giving them a polar opposite makeover. His latest subject is the popular performance of Travolta and Newton-John's Grease soundtrack favorite, "You're the One That I Want."

In this case, he gives the infectiously dancy song more edge, turning it into a death metal track. Imagine our surprise when the sexed up Olivia Newton-John takes a drag off her cigarette and delivers a guttural "Tell me about it, stud" to the truly shocked Travolta. Now the eyebrow raising reactions of all those onscreen seem totally legit. And, appropriately, Travolta and Newton-John are both decked out in solid black, so the death metal makeover is complete.

Add in some nifty riffing with some speedy licks and the song becomes something you can head bang to rather than shake your hips. And if one death metal growl floats your boat, remember this is a duet and you get a back and forth of rough vocals. How often do you get a death metal duet?
