Watch A Game Of Thrones Opera Cover

Forte Tenors, a classical a cappella trio known for their appearances on America's Got Talent, put together an operatic version of the Game of Thrones theme song, and to no one's surprise (and with a little help from MTV), it's gone viral online.

The song also features a lyrical track that neither we nor MTV can make out; perhaps a fan can enlighten us as to whether it's (a real or Martin-created) foreign tongue?

Check it out below.

Game of Thrones returns to HBO on April 12.
