I was most impressed with Celine Dion's performance of Greatest Love of All. It is depressing seeing Mariah at 42 and even Christina A at 31 not being able to, or struggling to hit the notes they used to hit with ease. However, at 44, Celine's voice remains golden. Jennifer, Mariah and Christina should ask Celine for tips on preserving their voices into middle age. Celine Dion's Vocals..... PERFECTION.....
