Have you noticed that "777" was also on Michael's clothes in This Is It?
The numbers were not there on his shirt when he was still rehearsing at the Forum. Take a look for example the beginning of Thriller and there's nothing on his shirt.
If you watch carefully you can see the "777" made of rhinestones on his shirt in the end of The Way You Make Me Feel where they are talking about those 8 bars and putting them back.
Sorry, if this has already been discussed. I just found out about the numbers
