Yada Yada K

Weaving magic out of thin air

“Yada Yada K is an example of everything that is good about comedy”. ★★★★★ Remote Goat

This is witty comedy woven out of thin air that seems as effortless as it is hilarious. ★★★★ Everything Theatre

Yada Yada K is on the last Tuesday of every month at the Camden Head in Camden and sees a mix of newer groups performing for the first time, experienced groups trying out new forms and a headliner from the improv circuit. Previous shows have featured Paul & Cariad, Showstoppers, Do Not Adjust Your Stage and more.

A Harold night at the Nursery Theatre

Full of absurdity, immediacy and fantasy, it was a delight to behold.


Everything Theatre

Beats by Del is our monthly Harold Night at the Nursery Theatre. The Harold is an improv form created by Del Close in Chicago and is at the heart of most Chicago-style long-form improv. Every month Beats sees 4 of London’s best improv groups attempt to approach this form and all its weird and wonderful derivative.

So what is a Harold anyway?

The Harold is a classic improv form developed by Del Close at the iO in Chicago.

Who is Del Close?

Del P. Close (March 9, 1934 – March 4, 1999) was an actor, writer, and teacher who coached many of the best-known comedians and comic actors of the late twentieth century. In addition to a prolific acting career in television and film, he was considered a premier influence on modern improvisational theater.

What are some Variations on the Harold

There are so many long-forms based on the Harold ... and the beauty is that you can make your own - sometimes during a show.

… this one time

Improv inspired by your true stories

Everyone has at least one weird and wonderful story they love telling. Want to share yours?

“This one time” is a comedy show where a specially assembled selection of some of London’s best improvisers use monologues, poets and musicians as the basis for scenes. With very special guest monologists each month. We also invite members of the audience to share stories if they have a burning desire to tell one.

The third Monday of the month at The Miller in London Bridge. Tickets £5 8pm

What do I have to bring?

A story, a memory, a poem or just an interesting idea that you'd like to inspire the cast with

Can't I just sit back and watch the show?

Of course. We love when people share things on stage as our audience is fascinating - but we're also going to be inviting poets, musicians and other monologists down to talk about their lives, so it will be interesting regardless

Who will be performing?

We try to get some of the best improvisers from teams across London - and beyond. It's a great chance to see people play in combinations that you wouldn't normally see

I'd like to be a guest speaker!

Great! Email and tell us more

New to improv?

If you’ve not done any improv at all before and want to try it out, there are a few places we can recommend. Although improv performances are made up on the spot, improv generally works on some loose principles that are well worth understanding before you put yourself in front of an audience. Going to a class/session will help you meet lots of people who have the same desire as you and give you a safe space to find out what its all about. You’ll hopefully have a lot of fun with it too.

  • C3467X have energy popping out of their ears. Watching a show is like having The Wire/Downton Abbey/The Muppets simultaneously and intravenously fed to you. They are a one-of-a-kind gang of improvisers, so unique no words can describe them; better left to a mash of numbers and letters: C3467X.

  • Lost my voice a little bit from laughing and cheering so hard.

  • Will be making this a regular highlight in my calendar. Go!

  • Yada Yada K is a night of London’s best improv comedy acts, in a weird shaped room, on a tiny stage. What’s not to love? With the audience getting the chance to join in on stage it ends up more like a rabble of friends than a crowd of strangers. It’s like a warm custard hug.
