Apart from the amazing video/it ai aspect of their act, the actual vocalists are phenomenal!!! The guy, posing as Simon, who performed Defying Gravity was absolutely awesome!!! Though they are standing in as basically background to the performance as anonymous artists posing as the judges….let us please give thanks to their talent as individuals! They are great singers and should be applauded for their vocals and own talent!!!! 
So sad that we don’t even know their names or background
