Laura: "Burning Buildings"
A chorus of doxies organized into a girl-group from across the ages: "Sweet Painted Lady"
Aristede: "Tiny Dancer" (he sings it to his knife) (Encore, "Sartorial Eloquence")
Angelique: "It's Me That You Need"
Burke: "Take Me To The Pilot"
Gabriel: "The King Must Die"
Josette: "Come Down In Time"
Hand of Petofi: "Bitter Fingers"
Julia: "Meal Ticket"
Barnabas: "Better Off Dead"
