i agree it was a bad performance but janis said that amy didn't want to do it & self sabotaged it (which is not new). however, it was incredibly unnecessary to speak about it considering it was four years later and more information about amy's issues was publicized. in 2010, surely charlotte should've known amy was struggling and recovering from a dark place. even if she was unaware of amy's problems (highly unlikely) she saw something that night when she looked dead at amy singing "you're playing with your life, this ain't no truth or dare..." plus who even is she? i bet most, if not all views are/were for amy.
