I saw it and it was a mess. As I recall, it was done as a play within a play -- maybe a history lesson - and was always very confusing. It was one of those shows where you sat there incredulouly questioning how such talent could produce such a mess. Personally, I did not appreciate the score as a whole on first hearing, because what was around it was so bad, sorta like Merrily, We Roll Along & Mack and Mabel.
Take Care of This House was excellent...the song was beautiful and Patricia Routledge is one of the warmest performers I have ever seen. She also had an incredible number that woke up the audience, where she sang as two First Ladies, one passing the baton to the other. I forget it's title.
Otherwise, it was ruined by a book that was a mess -- maybe it ended to be presented more like Assassins -- and an uncharismatic performance by Ken Howard. At the end of the show, the audience barely applauded (and there were a good number of walkouts at intermission).
Finally, between this and Darling of the Day, Patricia Routledge has to be my favorite stage performer who I only saw in two shows, both of which were monster flops (although I did love Darling).
