I was there at Stephen's birthday show! Laura stopped the music and made the entire audience sing happy birthday to him after curtain call.
There was non-birthday related but amusing blooper as well. During Not That Kind of Thing... Laura forgot to birng out one of the shopping bags, so she starts to say her line... then realized about halfway through that she didn't have it "You mean, like that table cloth you forced me to buuuuuywhere is that thing? What happened to it? Well, anyway, it was UGLY." And she and Stephen spent the rest of the scene trying not to completely break character. After he does his prancing around they were ad libbing "Where the hell did that tablecloth go?" and such. I died laughing (and then went and drunkenly sang "Come Out of the Dumpster" at a piano bar, but that's another story entirely).
l love you without knowing how... or when... or from where.
I love you straightforwardly, without complexities or pride.
I love you because I know no other way than this.
I believe in fate
But it's up to us to follow through
