For those who haven’t yet experienced the live phenomenon that is ‘Showstopper! The Improvised Musical’, the show is a fully realised musical created on the spot from audience suggestions. The cast transform suggestions for settings, genres, musical styles and even the name of the show into ingenious storylines with hilarious characters.
