I think James was proposing a more hypothetical situation. Obviously, its rather popular on here to be immediately negative... so you're just trying to fit in with the cool kids and I forgive you for it. Why not instead of being totally dismissive, answer the actual question... and then be dismissive or bitchy or whatever. But at least give the poster respect enough to answer their question.
I think Jennifer Saunders would do a good job. She's so funny and can sing pretty ok. But, I think she's kinda of a bigger deal than the size of the part. But, as far as fit goes... I think she'd be great.
Jesus saves. I spend.
