Morning radio reported that there was a rumor going around the whole Vonzell thing - and according to that rumor (don't know how credible it is) a family member of hers was diagnosed with cancer -- her father. So if it's true, I guess it makes sense.. she's singing "how do i live without you" and gets choked up and says it was hard seeing her father there.
Personally I have nothing against Carrie. For me, she's an OK singer, but she still has that deer-in-the-headlights look most of the time.. like she's not very comfortable on stage. Stage presence is key!
Vonzell is def. my fav. between the 3 because she picks the hardest songs, and usually nails them. The songs she picks always show her range, and she looks comfortable on stage and has a good time up there. (With the exception being of course her first performance the other night).
Bo would be my second fav b/c of his personality and his voice.
Carrie would be my third not b/c I hate her or anything, she just hasn't "WOW'ed" me at all. She's a good singer, but probably not the best. That's just my opinion though
