The two-part show’s movement director was in rehearsals with the cast, using some Imogen Heap music as inspiration. Then he decided that he wanted more. “‘The first I heard about it was pushing my baby at the time in a very muddy field with a pram,’ Heap recalled. She got a call from Hoggett who said he was working on a project for which they had been temping her music in workshops; he wanted to know if he could keep using it.”
