The Masterson Inheritance was a BBC radio show which mixed improvisational comedy in the style of Whose Line Is It Anyway? with a parody of Generational Sagas. Each half-hour episode would see the cast (Josie Lawrence, Paul Merton, Phelim McDermott, Caroline Quentin, Lee Simpson and Jim Sweeney, several of whom were already regular or semi-regular players on the UK version of Whose Line) be given a particular historical setting and, incorporating suggestions from the audience, improvise a new chapter in the saga of the irrepressible Masterson clan. One of them, usually Lee Simpson, would act as Narrator and keep the plot running, while the rest would play the various characters that appeared, always ending up with multiple roles.
