I don't really disagree with you. I wouldn't put her in the top 3 Tuesday night, though. She would be great in "Chicago" playing Matron Mama Morton. It would have been a hoot to hear her sing "When You're Good To Mama" if AI has showtunes night again.
I would pay top dollar to see and hear Mandisa reprise the Nell Carter role in the next Broadway revival of "Ain't Misbehavin"!
I loved Mandisa's voice and her verve, but she was miscast as an American Idol.
