There were some amazing performances at the "One World:Together at Home" Broadcast Saturday night, but this song has to be the highlight of the show for me. Global Citizen is a social action platform for a global generation that aims to solve the world’s biggest challenges. On our platform, you can learn about issues, take action on what matters most, and join a community committed to social change. We believe we can end extreme poverty because of the collective actions of Global Citizens across the world. Celine Dion, Andrea Bocelli, Lady Gaga, Lang Lang perform "The Prayer" during One World: Together At Home on April 18.
