As part of Sunday's American Idol finale, Lionel Richie went back to his roots with a performance of the classic "We Are the World." In a nod to the original, Richie kicked off the song before he was joined by winner Just Sam who was then followed up by finalists Jonny West, Dillon James, and Francisco Martin in a rather interesting New York City setting. There was also an appearance by fellow judges Katy Perry and Luke Bryan, who seemed to be living their forest fantasy as they were superimposed on trees.
The current American Idol finalists and judges were also joined by Idol alums Scotty McCreery, Lauren Alaina, Kellie Pickler, Laine Hardy, Gabby Barrett, Alejandro Aranda, Jordin Sparks, Katharine McPhee, Phillip Phillips, and Ruben Studdard. Watch the full video above as the performers literally become the world.
