One Night Only: The Greatest Musical Never Written is a musical comedy with an all-star cast and a five piece orchestra. The show follows the conventions of a scripted production but is completely improvised, dictated by spontaneous audience suggestions. Each performance has an original plot, characters, music, songs and choreography. It feels like anything can happen on stage and it does! If you enjoy musicals, improv or just like to laugh - you will LOVE this show.
