OUR HOUSE by Tim Firth. Directed by Matthew Warchus. Music by Madness. Cambridge Theatre 2002/3. Winner of Olivier Award for Best New Musical. The “sliding doors” style narrative required the lead actor to be seemingly in two places at once. The many instant quick changes resulted in a Guinness World Record for Paul, the director and star of the show for the most number of costume changes by a lead in a musical.
