Sounds like a great program but, unfortunately, I can't get GOLD.
In deciding who is Britain's greatest comedian, names like Kathy Burke, Simon Munnery and Bob Mortimer are (ironically) an absolute joke. Although all three of them are splendid at what they do, I can't imagine anybody in the world thinking that they have the remotest chance of being deemed Britain's greatest comedian.
I suppose the term "comedian" includes stand-ups and comedy actors/performers but I think the man or woman in the street when thinking of a comedian, imagines a stand-up.
If we're talking about stand-up, my own favourite by a goodly number of light-years is Stewart Lee.
Leaving my own personal preference aside and looking at the picture from all angles, I can see Billy Connolly and Jimmy Carr in the running but I have to say it's very difficult to see past the legendary and incomparable Ken Dodd.
If we're allowing non-stand-up comedy performers into the picture, the blindingly obvious top contender from that group is Ronnie Barker.
