I read the Everything was possible book recently and you’lll find that the intermission situation is a lot more complicated than sometimes portrayed. The authors didn’t seem to write it thinking it worked perfectly without an intermission - it seemed to be they wrote it and were rather mixed at first about where one could go (if anywhere). There were several discussions and viewpoints in the team, with previews of the show in the 70s playing with both no intermission and an intermission at different points - after Who’s That Woman or Too Many Mornjngs. Even the way the show resumed was debated and changed several times. Eventually they settled on no intermission because that’s what they felt worked best. But it wasn’t as if this was the original set-in-stone vision for how the show was going to work - they knew very early on it was difficult to manage with or without an intermission. It probably reflects a flaw in the show.
"You can't overrate Bernadette Peters. She is such a genius. There's a moment in "Too Many Mornings" and Bernadette doing 'I wore green the last time' - It's a voice that is just already given up - it is so sorrowful. Tragic. You can see from that moment the show is going to be headed into such dark territory and it hinges on this tiny throwaway moment of the voice." - Ben Brantley (2022)
"Bernadette's whole, stunning performance [as Rose in Gypsy] galvanized the actors capable of letting loose with her. Bernadette's Rose did take its rightful place, but too late, and unseen by too many who should have seen it" Arthur Laurents (2009)
