Its really weird that people question michael in this attire and even pointy shoulder attire aka "penguin man" because when he sang that intro to speechless I was blown away. Even when he performed "wanna be startin somethin" and "jam". As for "penguin man" "human nature" or "I just can't stop loving you"? Oh I feel offended that it the feeling of those you couldn't tell it was michael. I want clues too but the last thing I wanna do is believe that there was doubles. I believe michael looks different in a lot of shots due to make up or not shaving or even the weight loss that was spoken of by him and his crew due to his creative mind not lettin him sleep or eat. I hear too much about there was no anti gravity lean or moon walks? Well look closer he does moonwalk and although there is no lean he replaced it with some more pretty sweet dance moves for the rehearsals atleast. Everybody expects so much from him and yet I waited and waited for his return to the stage after so long I believe it was the 30th anniversary show and I bought my this is it movie tickets when they went on sale and watched it twice in the theatre. So understand when I watch this is it I don't expect him to break his body during rehearsals if you think otherwise check youtube of his tour rehearsals he doesn't do as much as he did in this is it. Ok I'm rambling now. Sorry.
