Jonathan Pie (Tom Walker) is roped in last minute to host BBC radio's most popular phone-in show. Basically there's no one else available. Out of his depth and up to his neck in it, Pie manages to just about hold it together. He muses on the state of the BBC and in one breath is singing its praises and in the next he tears into it with his usual gusto. Jonathan Pie ..... Tom Walker Jules ..... Lucy Pearman Sam .....
