So we've heard since the movie came out that before Light Man opened This Is It,there was a video montage of different documented events both with important world happenings (i.e. Royal Wedding,Barack Obama's election as president,etc.) along with clips of past MJ videos entitled "Glimpses and Flashes". But there's never really been a solid notion as to what the entire video would have included,other than the five second snippet shown at the beginning of the movie. There's never been any indication of what music and what video clips would have been used beyond what's already known. I'm fairly positive that the musical piece that Michael Bearden shared on MySpace back in the day was the introduction music for Light Man and had nothing to do with the Glimpses & Flashes montage prior to the Light Man section of the opening of the concert. What would you hypothesize the opening being within a two-minute timeframe? I was thinking it would have been an extended version of the HIStory song opening & closing with all the different audio clips from world events but with a visual added to it. But at this juncture it's all hypothesis and nothing concrete,unless there was a way to get in touch with someone who worked on the show and ask them what it would have included.
