If there's one thing you can't prepare for, it's a spot of impro. The Festival Of Improvisation is defining spontaneity as we know it by bringing 20 shows to one venue, for one week only. It's gonna be insane. Come and can catch some of your favourites from the cult TV show Who's Line Is It Anyway in Andy Smart's Improv All Stars, including Steve Frost and Steve Steen. Over 16s only.
