There is a misconception about Bernadette because of what happened to her pre and post opening. She got sick about three weeks into previews, and then re-aggravated the problem soon after the opening. She missed around 11 performances total during her illness. Once she recovered fully, she sang the role 8 times a week, in good voice, missing almost no performances for the entire run.
And I have to agree that Betty Buckley sang the score thrillingly. She's probably not an ideal match for Rose, but she did things with those songs that I've never heard before. I've seen Gypsy a lot, but it's the first time that "Everything's Coming Up Roses" really scared the **** out of me,
Begin at the beginning and go on till you come to the end: then stop.
