You don't need to dig through what he did behind all the fancy clothings and exaggerating stage settings to know that...just look at how he does on stage. His vocal is very stable live and his dance moves are powerful and clean. From singing and dancing to details like hand gestures and facial expressions, it takes a lot of practicing to perfect. I believe that whoever sees him perform on stage will prasie him for his outstanding performances, be it a fan or not. The sweats shed won't betray him.
