The younger Whitney blew them away, not the current or the Whitney of the last few years, she's lost it completely IMO, and it's unfortunate as I really liked her range, especially the higher notes.
I've always liked this version from this little girl, Charice, listen to this girl's range, some amazing pips for such a little girl.
