Here's the legendary Christine Ebersole doing a number at the Drama Desk Awards,
We saw her marvelous understudy, Maureen Moore, and were all freely weeping at the end. I know it's Broadway heresy to say it, but honestly, we all preferred Ms. Moore, whose voice is better, sounds more like the actual Edie, and who was more nuanced in her performance than I've seen in Ms. Ebersole's several clips of the performance.
Haven't you ever seen the documentary Grey Gardens?? Oh, for heaven's sake, get it from Netflix right away.
SisterBang has adored it for "years and years and years." She's so staunch.
