Did you make this video or you just took it from the internet?
Because to me it is like picking useless clues from anywhere.
This whole thing about the sun is NORMAL. Clouds does exists and when you are shooting a movie outside or with outside backgrounds, it is something you have to deal with. Sometime when a cloud is passing, you have to "cut" and wait for the sun to shoot again, for the visual continuity. And if sometimes one plan is sunny and the other plan straight after is not, it is because they worked the interview in the editing, to get a nice continuity of the audio too. Sometimes, you have to make some sacrifice in the editing and make some heartbreaking choices, like sacrifying the visual continuity in order to get a better audio continuity.
And the smile in the bush? Come on! It is just random shadows.
And one important thing is the fact that when the news of MJ death came out, people called ME, a random fan, to ask me the same question: "Are you ok?" Because my friends know that Michael is a influent person in my life. They know I fought for him big time. So it is normal that they were worry about me. And this is the same for Lisa-Marie, who shared her life with him!!!
If she was my friend, I would have call her too to ask if she was ok! In my opinion, it has nothing to do with the song.
I do believe MJ is still with us, but I do not believe he's leaving clues everywhere like that.
