As a big fan of his and as many as we are to him , I have been Looking over preview Clips on "This is it" footage and i have noticed that Michael was swaying his arms forwards and backwards a few times and collapsing his hands together in front Which gave me an interest in why he was doing that.. Was it that he was too close of the guy that was staring at him or was he too warm. ? Just had given me an interest on the detail. x x x thank you Ciara
