The One World: Together at Home special couldn't have ended any more beautifully.
Céline Dion teamed up with Andrea Bocelli, Lady Gaga, Lang Lang and John Legend to close out the global event with a powerful surprise performance of "The Prayer."
"I pray you'll be our eyes and watch us where we go. And help us to be wise, in times when we don't know," they sang, collectively. "Let this be our prayer when we lose our way. Lead us to a place, guide us with your grace, to a place where we'll be safe."
