I don't know if it's just where I was sitting (dress circle center), but I thought the orchestra was pretty rough at times. Some of the soloists sounded a little weak, there were songs when they seemed almost completely off the beat from the singer, and a certain lack of fullness, especially when the orchestration was less sparse. I don't know if it was the acoustics, the conductor, or lack of rehearsal time, but something seemed a bit off.
That said, there were some AMAZING performances. Standouts to me were Christine Ebersole, Karen Ziemba and everyone in Who's That Woman, Jennifer Holliday, Norm Lewis/Nikki Renee Daniels, Harolyn Blackwell and Mikaela Bennett, Santino Fontana, Kate Baldwin, and Kurt Peterson (I audibly gasped when he said he'd be performing Live Laugh Love).
I liked Ted Chapin and Kurt Peterson as hosts, but I wish there were a few more anecdotes about the original production (though I enjoyed the one about the former Greer Garson lyric). I was also expecting Michele Pawk to be getting her own song instead of just being in the dance ensemble for Who's That Woman, but ah well. I'm assuming Kate Baldwin and Beth Leavel replaced Rachel Bay Jones and Donna Murphy, respectively, and while it would've been wonderful to see their take on the songs, I'm not all that mad about what we did get.
All in all a very worthy concert experience (especially considering the very reasonable ticket prices!) and I'm so glad I came.
