I do not think she is necessarily young, but I did want some sort of tough broad to play Hattie. I love Shutta's and Stritch's "Broadway Baby"s because the way they sing it--and their personas--give a sense of irony to the lyrics themselves, there's a lot to be done with subtext. While I love Bernadette Peters' rendition in concert, I do not think the cute, funny take on this number could work within the context of the show.
I've never seen the show live so maybe my take is erroneous but this is one of my few concerns with the concert.
Honestly, I just can't wait to see Victor Garber, Donna Murphy, Victoria Clark, and Michael McGrath singing in unison:
"Waiting around for the girls upstairs, thank you but never again. Life was fun but oh, so intense, everything was possible and nothing made sense. Back then when one of the major events was waiting for the girls upstairs..."
"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"
