When you're putting together a show for The Second City, you go through something called "process." You take the show that's currently running, and over time, you start to replace scenes in that show with new ones you have been working on during the day with the cast, the musical director, and the director. You're generating tons of new material — sometimes through improvisation, sometimes not — and it's material of all kinds: sketches, songs, blackouts, monologues, improvisational pieces. You try out the new material in the show that night; sometimes it works, sometimes it doesn't. But once the old show has been entirely replaced with new scenes, congratulations: you are the proud co-parent of a new Second City Mainstage revue. You run that show for ten months or so, and then you start all over again picking it apart and making a new one. Process.
