Celine Dion on The Oprah Show
These vocal powerhouses first performed together during the 1999 Grammy® Awards, when music producer David Foster asked Josh to fill in for Andrea Bocelli and sing "The Prayer" with Celine.
So I see this young kid, and I'm like, 'Okay, sure and you know the song?' And he said, "Yes, I think do." And he took the microphone and when he started to sing, he couldn't be any more powerful than that," Celine said. "This kid was incredible."
