[iluvmjforever2009]

I been watching the Jackson 5 In Mexico 1975 almost everyday I recommend anybody who Is a fan Of Mj look at this video. You will see that Michael was already so ahead of his time as a performer at the age 17 which he was here, that all he did was just refine what he was already doing!! I'm wondering If anybody can tell me when did he start doing his famous spin!! here is the link to the videos http://www.youtube.com/watch?v=wfHhe5DuqMU&feature=related
