Perhaps we live in more conservative times than we like to think, and it’s only OK to mock the “establishment” if by that term you really mean the long-gone men who looked and sounded like John Cleese in Monty Python’s Ministry of Silly Walks. It’s a different story if you want to knock today’s hegemonic elite – the baby boomers who run the television channels, advertising agencies and publishing houses but still like to think they’re outsiders.

The unfair critical response to this extremely well-made and enjoyable play sounds like the whine of an establishment that wants to believe it isn’t one, an establishment made up of real-life Margot Masons who need to believe they are still young and rebellious, that there’s a stuffy bourgeoisie out there that needs to be shocked and challenged. The funny thing is that the new establishment has been challenged in a delightfully joky way by this play and apparently can’t take it.
