I think Williams was a good choice for the Witch. She is no Peters but she sounds fine on the recording. Unfortunately, Sondheim changed the lyrics to what IMO is the best song the Witch gets in the show, "Last Midnight," the new lyrics are soooo boring and unnecessary.
I LOATHE the new ending to "On the Steps of the Palace," can't stand listening to it AT ALL, mostly because I think Molly Ephrain and Adam Wylie made an awful Little Red/Jack pairing.
Benanti sounds great in the song, but Kim Crosby gets every nuance, comic detail, and torment implied by the song. She may not have the impressive vocal talents of Benanti, but she certainly acts the song a dozen times better(and I'm a fan of Laura Benanti).
And don't get me started on the Baker and the Baker's Wife. Ugh!
"Some people can thrive and bloom living life in a living room, that's perfect for some people of one hundred and five. But I at least gotta try, when I think of all the sights that I gotta see, all the places I gotta play, all the things that I gotta be at"
