Just Not Cricket!, a three day long festival focusing on British improv, held in Berlin in 2011.
Someone is making a film on the history of the British improv scene (to be released in 2013!), and a couple of great videos from this one are uploaded on Vimeo. Watch Lol Coxhill and Alex Ward at Just Not Cricket! in this very blog, and run all the way over to Vimeo for Tom Arthurs, Steve Beresford,Phil Minton and Eddie Prévost.
