Interesting you mentioned Grey Gardens, besty, because Jessica Lange as Big Edie in the HBO film insisted she challenge herself and do her own singing for the first time on film. We'll see if it was a wise choice to let her or not.
As much as I'm not a big fan of Lange, I rather hear her trying to take a jab at Big Edie's singing than someone like Julia Roberts trying to even tackle something as precious as "Another Winter in a Summer Town," there's an argument for dubbing if there ever was one. They should use a body/face double for that one as well.
