Huh, I must have been lucky when I went last Saturday eve and Jane come out! Didn't realize she doesn't always. But it's early previews and who knows who might have to stick around for notes or rehearsal or whatever...
Gavin Creel didn't come out for me, and neither did Michael McGrath (he pretty much never did for OTTC either so I didn't expect him).
I have to admit, I found the whole ordeal Zach Levi did a bit much. I didn't know him at all before this, and basically went to see the show for it's reputation, Laura Benanti and Jane Krakowski. So I was surprised to find so many Zach fans at the SD, all very hyper teenage girls. And then the whole thing with the boombox and the doing the line twice, geez, really? He seemed really nice, but it was too much of a show for my taste, and when a star asks you if you want to take a photo and you're forced to say "No, thanks" it's just awkward... It was like... as if in his mind the whole SD and everybody who shows up was all just about him and the whole thing felt uncomfortable to me.
That being said, both Laura and Jane were very sweet, Laura took photos as well, Jane didn't. But both took a moment for every person there, which I really appreciated.
