I'll just say this, and then sign off for the night? There is a uniqueness to Michael's voice, that no "official" voice analysis can convince ANYONE of, if they can tell the difference. The difference is, that Michael's REAL voice is unmistakable, and can be identified by the idea that he is singing right TO us.. . to each, individual person, as real as listening to someone who is right there, recounting a story. For me, the BN song did NOT do that. And Keep Your Head Up does. That is HIM, on that track.
G'night.
AMEN! I second that! you can't mistake his voice......his grunts, his ad libs....this is Michael!
