There's no such thing as an "original copy of Dangerous" with Man In Black and Joy included. This person is bullshitting to the core.
They refer to the Flight Only Promo CD.
This Flight Only Promo CD (of the 'Dangerous' album), which Sony Music's top executives exclusively listened to it during a flight, was allegedly the original copy of the 'Dangerous' album.
This Flight Only Promo CD allegedly included few brand new tracks that were planned for the upcoming 'Dangerous' album (such as, 'Men In Black', 'Monkey Business') and some other songs.
It appears that this story was just a myth among his fans (i.e., this Flight Only Promo CD never existed).
