A sold-out Dome was testimony enough to the enduring affection held for I'm Sorry I Haven't A Clue.

Like me you’d probably have expected the hundreds of devotees of Radio 4's antidote to panel games thronging the bar on Saturday to be middle class, middle aged and white.

In truth they were the majority but there were enough of a smattering of youngsters, hipster beards and trendy girls to suggest something else was going on here.

I’m Sorry has always been the punkish cousin of Radio 4 comedy even though it’s nudging 45 years-old.

It’s the show’s eccentricity that makes the audience a little more diverse than say Just A Minute, the host of that show, Nicholas Parsons, here getting a hilarious going over from our own host, the excellent Jack Dee.

In fact I’m Sorry couldn’t be more quintessentially, quirkily British if it came out in a top hat sporting a handlebar moustache and riding a penny farthing.

So we joined in the stupid childish games, played our Kazoos with gusto and laughed ahead of the curve so well worn and beloved are the routines.

And of course as liberals one and all we chortled the most, but with delicious guilt, at the Everest-high pile of innuendo that was the rocket fuel of the show.

To prove that right-on doesn’t have to be po-faced or politically correct the biggest laughs were reserved for the outrageous double entendre cruise missiles pointed at Lionel Blair and scorer Samantha.

A latter joke about her date with an Italian ice cream maker involving the nuts on a Neopolitan was not just end of the pier but middle of the Channel.

The panel, legendary Barry Cryer, Tim Brooke-Taylor, newbie Miles Jupp and Jeremy Hardy were uniformly excellent, the latter proving he could really do comedy not just substitute laughs for left-wingery as he does on the News Quiz.

But it was Dee, a perfect heir to Humphrey Lyttelton, who really shone, his jaundiced, going-through-the-motions, delivery perfect for this most peculiar of British institutions.

Four stars
