For those old enough to remember when we had evil censorship in the UK, governed by the Government (go figure), you will possibly remember Kenneth Tynan.
For those of you that don't know of him, he was the first person to say "fuck" on British telly (I think) and as a critic, did us all a big big favour by fighting with the absurd censorship laws that theatres, cinemas and authors had to contend with.
Watch BBC4 tonight at 9pm. is what the Beeb say about it.
is informative, too.
