I think that MC in addition of being the narrator he plays the biggest key charterer of the film because without him the truth won't be as clear as the way that he explained it. The ways that he was reacting and the lyrics and the moves of the song explained how the Germans are living outside the Kit Kat in great poverty. For example the dancers moves were more of limited and restricted than the ones in the 42nd street and the size of the theater was not as big as the one in the 42nd street. However this explains that the Germans were in great debt and loss and their freedom and beliefs were restricted by the dominant Nazi Party. I agree that you used Verisimilitude because it was definitely there, the theater's art reflected real life.
