I thought this finding was funny because I actually watched this video like 20 times and probably cried good 3 times. There were more or less known as "Il Trio" or even "TRYO" at that time. Not sure if any of those were the group's official name. Someone please enlighten me :'(
As many of you may know, We Are the World 25 for Haiti was released on February 2010 as a charity song for the Haitian people. You can even see their names listed on this Wikipedia page! Anyway, I would never ever thought of a possibility of Il Volo featured in this music video until ILTRIOTV on Youtube said so. I'm guessing either this was Il Volo's official account before they changed the name to Il Volo. Anyway, here's the music video for We Are the World 25 for Haiti. Do you see them?
