I’m fascinated by Garth and Kat. [Laughs] Thank you!I think I know how it works, but, yes, how does it work? Does Armisen lead?Yes. He definitely starts and I just try to follow. We don’t rehearse. The first time we do it that week is literally at the dress rehearsal.Does he change the words between dress and the live show?Oh yeah, nothing is the same. That’s why we don’t ever think of anything beforehand. If anything, we will be like, “All right, well this is a Halloween theme, so, here’s ‘pumpkins, witches, ghosts.’” We’ll think of things people can sing about, but, actually even when we do it, that all goes out the window. It’s the most fun I have because so much of the show is writing, working, deadlines, trying to figure things out, punching up your sketch, knowing you’re going to perform live. And that two and a half minutes of airtime is so freeing and fun.
