These two compliment each other well.
James with his screeching voice and simple lyrics and Pavarotti with his classic power. Pavarottis voice reminds me of the Niagra Falls. He opens his mouth, and his powerful voice just flows out with such power.
I like to start it at 1:35 where Pavarotti starts singing and then they both take turns singing back and forth.
Take a look/see, I think you will enjoy it.
