If you mean the dialogue before "Say Kate, can I ask you a question", you'll have to go through a company member or someone who already has the script, as it's not readily available to the publice yet
KATE Oh. Well, I'm a Kindergarten teaching assistant.
PRINCETON Right. But what's your purpose, your dream, your mission?
KATE Nobody ever wants to know that.
PRINCETON I do.
KATE Well, since you asked... no, I can't! I barely know you.
PRINCETON Aw, come on!
KATE Okay. When I was a little monster, I always wished I had a special place I could go. A special school only for monsters. Sure it's important to learn about the great figures of Western civilization, but so much of the canon leaves out monster art and history! And we as a nation are poorer for it. It was always my dream to start that special school for monsters. So that, in short, is my purpose. Uh, but I'm not an egghead. I like to have fun and “party”.
PRINCETON Oh. So, uh, you're level on the monster stuff?
KATE Uh-huh.
PRINCETON Ah. Well, you know Trekkie Monster upstairs?
KATE Uh huh.
Princeton Well, he's Trekkie Monster, and you're Kate Monster
KATE Right.
PRINCETON You're both monsters.
KATE Yeah.
PRINCETON Are you two related?
KATE What?! Princeton, I'm surprised at you! I find that racist!
PRINCETON I'm sorry! I was just asking!
KATE Well it's a touchy subject. No, not all Monsters are related. What are you trying say, huh? That we all look the same to you? Huh, huh, huh?
PRINCETON No, no, no, not at all! I'm sorry, I guess that was a little racist.
KATE I should say so. You should be much more careful when you're talking about the sensitive subject of race.
PRINCETON Well look who's talking!
KATE What do you mean?
PRINCETON What about that special Monster School you told me about?
No, no, that's most of the scene before "Everyone's A Little Bit Racist". The only other thing that happens before that but after "Purpose" is everyone describing what their purpose is.
and for the record, the recording only includes "say kate, can i ask you a question..."then skips directly to the trekkie part
"Grease," the fourth revival of the season, is the worst show in the history of theater and represents an unparalleled assault on Western civilization and its values. - Michael Reidel
