Luciano Pavarotti passed away today at the age of 71. He was the best-known opera singer outside of the world of opera, largely because of his "Pavarotti and Friends" series. He would sing with just about anyone. And though he is gone, he lives on at YouTube. After the jump, see Pavarotti duets with Barry White, Queen, Bono, The Spice Girls, Lou Reed, Meatloaf, James Brown, and more.
