Those are the nights that the usual tenant at the Ambassadors, Stomp, is dark. Showstopper! The Musical has played previous residencies at the Ambassadors and King's Head Theatre, and a BBC Radio 4 series of six special 30-minute improvised musicals was broadcast in early 2011.

According to press materials, "a writer has just one night to create a hit show to impress his producer. Stuck for ideas, he takes audience suggestions for a title, storylines and musical styles that they'd like to see in the show. The Showstoppers then create a musical from scratch based around that structure.

This format was created by Sticking Place artistic director Adam Meggido and veteran improviser Dylan Emery, both of whom worked closely with the late theatre maverick, Ken Campbell. This collaboration resulted in Shall We Shog? (Shakespeare’s Globe 2005); Décor Without Production (for The Royal Court Theatre 50th anniversary celebrations); In Pursuit Of Cardenio (Edinburgh Festival 2006); and the annual 50-hour Improvathon.

The Showstoppers are Chris Ash, Duncan Walsh Atkins, Ruth Bratt, Julie Clare, Dylan Emery, Pippa Evans, James Lovelock, Sean McCann, Adam Meggido, Philip Pellew, Nigel Pilkington, Oliver Senton, Lucy Trodd and Sarah Louise Young. Created by Dylan Emery and Adam Meggido, it is produced by Adam Meggido, Dylan Emery and Keith Strachan for Showstopper Productions.
