I will not reveal too much here the exact identity of the person. Because a user from here is following me on the networks and harassing everyone I talk to...
But to make a long story short, I did find the person but they didn't tell me anything about the status of the song... Either because it was just written and not recorded, or because of the DNA's... For most of the collaborators that I was able to interview, that's it. Anyway I'm pretty sure the year of the song is in the late 90's. She also wrote songs for 3T's second ever released album.
In any case, I have little hope that the song will be recorded by MJ.
