Tragedy: The All-Metal Tribute to The Bee Gees Does Slayer, ‘Grease’ and More [VIDEO]

This is one of those situations where you watch one video and you get sucked in and watch more and more. The groups cover of the Grease song "You're The One That I Want" is making the rounds, but it's the Slayer mashup that I think is hilarious.

The band is Tragedy: The All Metal Tribute To the Bee Gees. You can check out their page and check out a whole albums worth of metal covers, but I have a few videos to get you pumped up. This is some funny, but still authentic stuff. Get ready to lose about 15 minutes.
