Why doesn't Stephanie belong in Wicked? She was the first Elphaba (in readings), even before Idina Menzel came into the picture. She is completely capable of singing and acting the role.
I've said this many times, but her voice is too matronly for the role. Ive heard many recordings from different dates and cities, she sounds dull in each and every one. She just doesn't have the right sound for the role. But that's just my opinion. I know she has a fan base here on the boards.
