Ok, regarding people here who can't deal with the fact that MJ had HUGE mental and physical problems the last years of his life, well it's your problem if you choose to live in a make-believe world. Those of us who can deal with reality know how he died, and we've read the emails describing his last days, and we're mature enough to deal with those facts. I have nothing more to say about that.
Regarding everything else we've learned today, today was incredibly productive. To recap :
A MAJOR piece of information was right there under our nose the whole time, and none of us found it until today. So that should be a humbling experience for ALL of us.
All of the people who, for the last two years, have assumed that one Jason Malachi was the fake singer on the tracks, have now realized it was actually James Porte singing that "too bad" hook on "Monster". So anybody who thought that sounded either like Malachi OR MJ has just found out that their all-powerful ears are not so precise after all.
The post from the sound engineer PROOVES that MJ had indeed told the Cascios he was going to record the songs in London, so it proves that MJ at least knew about the songs. So the oft-repeated belief from the anti-Cascio people that MJ had not ever heard of those songs is proven to be false. It also shows that the fact that the Cascio songs were not on the list of songs MJ wrote down as possible songs for a new album is irrelevant : he still knew about the songs.
The Cascios told the engineer MJ had co-written the songs. Since they would have had no reason to say that if the songs had had NO input from MJ, it shows that MJ probably did "work" on those songs while he was at their place in 2007. Now, the extent of that work is unknown.
If MJ did know about the songs, and if he did "work" on them while in New Jersey, it stands to reason that, being in a studio with a couple of musicians, he certainly would have sung at least some of the lyrics into a microphone at some point.
Now, why were those vocals NOT on the tracks that were handed over to the engineer? Maybe it's because there never was ANY MJ vocals, in which case we would have to turn to the theory of an impersonator, which raises all of the implausibility issues we've discussed at length before.
Or maybe the vocals were not on the tracks because (aside from the fact they didn't want them to leak), they didn't have at that point any complete, usable vocals to put to those songs. ALL they had was those incomplete guide vocals, often in multiples takes that had broken down for a variety of reason, as is always the case when you record songs as you work on them.
So when MJ died, they took those incomplete vocals, spliced them and mixed them to make them presentable, and added a lot of James Porte, trying his best not to sound too unlike MJ so as not to be jarring, and put out those songs.
This makes perfect sense, and fits 100 % with what the official story has been all along.
