For just 10 more performances between 15 February and 25 July, audience suggestions will be transformed instantly into all-singing, all-dancing shows with unpredictable and hilarious results.

Even the title of each show is improvised. Highlights from the 2015 West End run have included: ‘Royal Flush’ set in the Queen’s bathroom, ‘Blatt Out of Hell’ from the Fifa HQ, ‘The Lyin’ King’ set in the Daily Mail newsroom; ‘I never tyre of Georgia’ set in Kwikfit in the Deep South and ‘Bricking It’, the sad history of the Guernsey Lego factory.

The Showstopper team nightly pull off something incredibly ambitious: they create a real musical from scratch, not just an improv night with songs but a full story with stories and characters you can care about, a live band of incredible musicians, and spontaneous but seamless choreography. With a BBC Radio Four series and eight years of festivals and touring to their name, The Showstoppers have delighted and astounded audiences around the world with their ingenious, unique blend of comedy, musical theatre and spontaneity.
