Achievement unlocked. Seen Whose Line Is It Anyway? live in London. Not quite the whole crew, but enough to be properly awesome. I remember the TV show many years ago. And now I've got fond memories of seeing them perform on the London Stage.
If you've not seen the show before I'm sure you can find it on YouTube. If you have, you'll know all about the improvisation, the lightning quick wit and the musical cleverness that goes on. It was one of those shows that makes your face ache from laughing. If you are in London and have a chance to catch one of the shows, you really, really should.
