In 2008, members of Impropriety were brought together to along with performers from The Sticking Place, London and DIE-Nasty, Canada to perform in Liverpool, Oh Wait part of the Ken Campbell tribute festival, The Metafex. From this, Impropriety was formed.
The improvathon format was created in Edmonton, Alberta by DIE-Nasty who have been performing 50 plus hour soap-a-thons since 1993. In 2005, the format was imported to the UK by Ken Campbell and The Sticking Place and have been performed around the country since, taking place in London, Bristol and Cork as well as in Liverpool. Lasting for anything up to 50 hours, these marathon events are the ultimate test for improvisers. Whilst some performers may take a break at some point during the event, traditionally some core cast members will participate for the entire duration, going one or two nights without sleep. The sleep deprivation reduces performers to their “lizard brain” state, where they become too tired to censor themselves, resulting in a unique and euphoric form of theatre. Many audience members stay for the full duration, sharing the sleeplessness with the actors
Since Oh, Wait, Impropriety has produced 2 more of its own improvathons, The Last Resort in 2010 and Dearly Beloved in 2011, both at The Kazimier. Both shows have featured guests from London, Bristol, Canada and America and have amassed a following of dedicated audience. members of Impropriety have also taken part in improvathons around the country and soapathons in Canada.
