Look guys, MJJC is becoming a more depressing place now with members turning on each other, insulting each other and thinking that their thoughts are right. Truth is, no one can give clear evidence on who is actually singing on these tracks except those who worked with Michael on them, and they claim them to be true.
Take this: if Shout and 2,000 Watts were never released before, and they were to appear on the album most of you would say that they were fake. But we all know that they are not. Michael's voice has just been heavily edited. The same could apply for the Cascio tracks.
Untill the release of the full album and everybody's listened to the songs thoroughly, then we can make a judgement on whether the songs are fake or not. But at the moment we can't, so we're just going to have to stick with our instincts and respect other people's opinions, because you never know if you can be wrong or right.
