A performance of the previous year's finale (Addams?) and the cast face upstage while the curtains close upstage of them. We do the cheering/congrats that go on backstage and then clear the stage to leave the three teachers.
After the summer...
The three teachers are congratulating one another on the show. Various people come and tell them they enjoyed it. One person comes and asks what's next? And a ridiculous suggestion ensues.
Student Speculation/New Boy in town
The teachers go to the staffroom for a "wind down" after the show (set DSL). They talk about their favourite moments from past shows. Centrestage, scenes and songs from the shows are performed.
Two teachers meet in the hall and say " I suppose we better think about..." They are interrupted by someone suggesting a ridiculous show. (cue scene) During the conversation they talk about potential cast. We see these individuals in spotlight elsewhere on stage. A suggestion of a quiet stage crew member from last year is made.
The "school show crowd" talk about the potential school show and have ideas of what could be. A new boy joins the group....
