Just some more random details/description for those not there:
There was, of course, tons of applause for everyone and everything. It was clear the audience knew the show that they were seeing: for example, Patty Goble even got lengthy, show-stopping entrance applause in recognition of her single hilarious scene as Jessica, even before she did anything. Also, during "It's A Business," everyone applauded when the main body of the song began (after "it's time for you to know why I really back this show"). Megan Sikora's Princess Kickipoo (??? no idea how to spell that) character also got her own entrance applause during Kansasland.
Almost everyone in the orchestra section was on their feet after "It's a Business." Not sure about the mezz. "Tough Act To Follow" got a standing ovation from maybe a third of the orchestra.
The end of the "Show People" number was one of the most emotional moments of the afternoon, even more so than the curtain call. From the fourth row, I could see the looks that everyone onstage was exchanging with each other. It's kind of hard to explain, I guess, but you can imagine what would be running though everyone's mind as almost the entire company performed their anthem about the joys of show business and show people for the last time. Everyone in the audience sensed it too, I think.
The producers came on stage at the end and invited all of the stage crew on, as well as William Ivey Long, Rupert Holmes, John Kander, Anna Louizos, and some others I wouldn't recognize. When the producer doing the talking (some old guy... not sure who) mentioned that Scott Ellis was in LA and couldn't make it, a lady in the orchestra section held up a blackberry and yelled that she was on the phone with him right now. Rob Ashford mysteriously didn't get mentioned or appear onstage... kinda like how he didn't get the Tony Awards he deserved the past two years. Although I'm pretty sure I walked past him before the show. Could have been someone else though.
"I just want a story and a few good songs that will take me away. I just want to be entertained. I mean, isn't that the point?"
