I saw her in the show, but I was very disappointed. Not her fault, but I knew the score with Bernadette singing it off by heart, but I couldn't get to NY soon enough and I missed her doing it.
From what I can remember, Betty did a fine job. The only things that bothered me about her performance were the things that still bother me to this day. As much as I admire and respect her talent, her voice is very abrasive at times. It's not a "pretty" sound. And the whole time I kept thinking I was seeing "the replacement", which didn't help matters.
No problems stood out, she did it exactly as I would have imagine Bernadette - but I felt ripped off. These days, I would go see a show on purpose to see the replacement, but back then all I cared about was seeing the person who originated the role.
I've seen and enjoyed Betty on stage in many things, Gypsy at Paper Mill and Sunset on Bway are the standouts for me. Also I worked with her on something years later and unfortunately, the stories I'd heard were true, at least that day - she was very, very difficult and demanding.
