I really hope she isn't the one who posted that entire quote.
I know I haven't yet said it but all the negative commentary Roger has been getting on her voice is starting to come across as unfair. I can see how she could leave much to be desired in Evita, but it simply isn't true that she can't sing and "isn't good." I'm aware that it's likely meant she isn't good as Eva and not that she isn't a good performer with talent, but after so much has been said, it all tends to get muddled and that's where it starts to feel misplaced.
That said, I've never seen Roger live on stage so I'm not doubting anyone but I do feel compelled to say that I've always enjoyed her Fantine in a soundboard and video I have of the Argentinian production of Les Miserables. She has a gorgeous and very strong voice and I would love to see her perform that role in English.
