He did get a note, ForestChav, but it's three single repeated notes on a piano and then you're right in, which is damn difficult to hear on stage above that crowd. Don't think they use earpieces. When Bianca did it on AGT that brief intro seemed a lot louder on my TV.




He wasn't far off, though... he knew roughly where it was in his voice, you can usually get close if you know that.
