Back for a fourth year and officially a Fringe favourite, Impromptunes returns with their signature musical mayhem. You suggest a title and seconds later the curtain rises on a brand-new musical, performed for the first, last and only time. Everything is made up on the spot – songs, scenes and choreography unfold before your eyes as Australia's finest improvisers create a full musical packed with hijinks, harmonies and hilarity. It's unrehearsed. It's unpredictable. It's a whole lot of fun. It's Impromptunes! 'Outrageously funny' ***** (TheatrePeople.com.au).
