I initially wrote the story as one long script then divided it into 12 parts. I planned on doing it as 13 parts but found it would have seemed too stretched out done that way. And there's enough narrative in the first day so that the story isn't really missed.
As the days go on the narrative shortens. I was going to have a paragraph of narrative before the song but found it hard to come up with material. And as it works out it's probably for the better. As the story gets going the narrative isn't really missed.
