Patti Cohenour was Ebersole's standby in Chicago, and I assume she'll be covering her again on Broadway, and I'd love to see her if she gets to go on. (Joanna Glushak, I believe, covered LuPone in Chicago.)
When I see the phrase "the ____ estate", I imagine a vast mansion in the country full of monocled men and high-collared women receiving letters about productions across the country and doing spit-takes at whatever they contain.
