Lucy Porter’s Fools Gold show is far more polished than when she first knocked it into shape last June at City Screen, York.

On that occasion, she shared a double bill with Canadian comic Tom Stade in an Edinburgh Comedy Festival preview en route to the Scottish capital.

On Sunday, almost one year later, she returns to York as part of Fools Gold’s 43-date tour.

“The preview went well because the City Screen audience are very nice and very forgiving,” says Lucy. “Now, if nothing else, I can promise it’ll be more slick and there’ll be fewer pieces of paper.

“There’s only so many times you can get away with unpreparedness. My curse is that I like to revise it as I go, so there’s always an element of danger; I think a little bit of experimentation is important, but 90 per cent of the show will be rock solid gold.”

That leaves ten per cent of any Porter show to be fresh, and she revels in putting that unpredictable ten per cent to the test in Yorkshire, where she performs regularly at the invitation of Hyena Lounge Comedy Club promoter Toby Clouston-Jones.

“There’s a very distinctive, definite personality about Yorkshire; it’s a country of contrasts, but one where people do speak their minds,” says Lucy.

“I read the local papers before the show and what I also tend to find is that people want to join in, which happens in a positive way, though Yorkshiremen can’t sit there without chipping in if you’re talking about Yorkshire.

“As a southerner, I was quite apologetic about it at first, having lived in Manchester, so I know about the antipathy, but now what’s more truthful is that I’m happy to have a fight. I’m up for it!”

Fools Golds completes a trilogy for Lucy after earlier shows on the theme of luck, love and happiness and the economy.

“I thought Fools Gold would be narrower but because my brain is tangential, I’ve spun off in different directions,” she says.

What has she discovered in doing Fools Gold?

“The main thing I’ve learned is that people like gold very much and they’re not prepared to give me any of theirs,” says Lucy, whose show delves into the history of gold and our obsession with the shiny metal, from King Midas, through the Aztecs, the alchemists and gold rushes, to Jimmy Savile and today’s rap pack.

Lucy also offers her personal take on the value of gold – not least why she is allergic to wedding rings – although she has a confession to make.

“When the show was in Edinburgh, it was all about never getting married… but by December 19, we were married – and we’d been together for years before that,” she says.

And no, she doesn’t really have an allergy to gold. “I found that out soon after I tried ingesting some 24 carat gold leaf. I didn’t have an allergic reaction,” she says.

Even though gold has its own E number (E173), it is harmless to ingest, as one audience member will be invited to test at her City Screen show. “My audience deserves to be fed with gold,” says Lucy.

Make the most of Sunday’s comedy gold, however, because Lucy is taking a year off from the Edinburgh Comedy Festival. “I couldn’t really fit a new show in with everything else. I’m writing a book; two chapters in,” she reveals.

“I’m not going to name it until it’s finished but it’s a sort of comedy memoir… about perms, Rick Astley and Croydon…”
