Here's the message from Impromptunes: 

After sold out seasons down under, Australia's premier improv troupe finally brings its riotous comedy to the UK!

The MC gets a title, and seconds later a never-before-seen musical begins. The only thing you know is that it will be full of highjinks, harmonies and hilarity.

It's unrehearsed. It's unpredictable. It's a whole lot of fun.
It's Impromptunes.

“An unadulterated concoction of excitement, danger and hilarity.”★★★★ Time Out
