Yes! I hope so too, that they will release the footage! Even though the whole thing is tragic as it is already, I think it's heartbreaking, that he left this world, without being able to one last time show, that he still has it!
To think that there is a fully conceived, developed and exercised show, a show on which Michael worked the last 2-3 months, a show that probably contributed to these tragic events, that could be forever hidden from the public makes me even more sick!
I don't want the WMA, wich is greatly portrayed as a desaster, to be the last time people saw Michael on a stage in a musical situation! I so hope that there is proper filmed footage of rehearsals and that they will release it! Maybe they even tested those Red cameras with filming the rehearsals!
