I love Amber Gray, too. Her "Charming" is a showstopper; Lilli Cooper, while certainly a great performer and arguably a more technically proficient singer, wasn't able to nail the song the same way when she played Helene in Boston. Amber Gray has real star quality and brings it to every role she plays.
