You don't need to be an opera fan to appreciate this video.  A singer named Marc Martel posted a video where he sings opera in the style of Luciano Pavarotti AND Freddie Mercury from QUEEN.  And it's actually really good.

First, he sings like Pavarotti and has a beard.  Then the camera spins around him, and the other side of his face only has a Freddie Mercury mustache . . . he even kind of looks like him.  And both impressions are spot on.

If you're an opera buff, the song is "Nessun Dorma" from the Puccini opera "Turandot."
