The Mitfords is a superb one-woman show by Emma Wilkinson Wright who focuses her attention on Unity, Diana and Jessica. In the early 1930s, Unity became Hitler’s lover and she lived in a luxurious Munich apartment confiscated from a wealthy Jewish family. The Führer, whom she nicknamed ‘Wolfie’, gave her the pearl-handled revolver with which she shot herself in the head shortly after Britain’s declaration of war. To carry out this bizarre act of self-sacrifice she chose a favourite spot in Munich’s English Garden where she used to sunbathe naked. In wartime Britain, Diana was held in Holloway prison and she complained bitterly about being separated from her baby boy, Max, and about the hefty sandbags that prevented daylight from reaching her cell. The lack of sun seems to have caused her more distress than the lack of son. Her sister, Jessica, tried to embrace Bohemian bliss in Rotherhithe but she struggled to cope without servants. ‘After hours sweeping the stairs I realised you have to start at the top and work down.’ This show is a must for Mitford connoisseurs who want to relive their favourite moments from the clan’s erratic history.

The Good Dad (A Love Story) is a harrowing yarn about rape and incest. The ironic title refers to a monstrous predator who impregnates his young daughter, Donna, on four separate occasions. Her family cover up these crimes but as Donna grows into womanhood she decides to take bloody revenge on the man who occupies three roles in her life: father, partner and rapist. Sarah Lawrie’s poised, nerveless performance is riveting.

The Briefing opens as a partisan rant by a pro-Dem comedian, Melissa McGlensey, who poses as a Trump fan in order to mock him. ‘Who can tell me what the “J” stands for in Donald J. Trump? Genius.’ She then adopts the persona of the Republican governor of Arkansas, Sarah Huckabee Sanders, and the show turns into an improvised press conference. Brilliant fun. McGlensey is exceptionally quick on her feet and she never hesitates when fielding questions. ‘What books would you ban from elementary schools?’ shouts somebody. ‘All the ones with words in them.’

All About Philosophy in 100 Jokes is a series of comic asides about famous thinkers by Oleg Denisov. Two examples. ‘Diogenes was a penniless hermit who lived in a barrel – which is what happens when you fail to provide basic mental healthcare facilities.’ And he jokes that Nietzsche’s decree, ‘if thou goest to woman, take thy whip’, came from the German philosopher’s keynote speech to the Zurich BDSM festival in 1876. He makes the same joke about Rousseau’s comment that ‘man is born free, and everywhere he is in chains’. The only problem is Denisov suffers from surges of uncontrollable rage. His show ends with a crazed diatribe about classic Russian literature, and a random opinion screamed at pane-shattering volume.

Inside No. 10 gives the excellent Matt Forde a chance to imitate Keir Starmer’s whiny, high-pitched delivery. And he adds a note of self-righteous pettiness that’s even more accurate than Starmer’s needling voice. To mock Nigel Farage’s financial woes, Forde imagines a pro-EU Coutts manager making a call to explain why the bank has withdrawn Farage’s account. ‘We’ve decided to stop the free movement of our financial services, Mr Farage, and to take back control of our investment portfolio. And, by the way, Leave means Leave.’ Forde tells us that all professional politicians are trained to avoid using the words of an accusation when issuing a denial. But this trick has yet to be mastered by Humza Yousaf. ‘I watched him on TV,’ says Forde, ‘and he actually said this: “The SNP is not a criminal organisation.”’

Rizal Van Geyzel ran the first comedy club in Malaysia for ten successful years until a female comic brought the whole thing crashing to the ground. Performing in a niqab, she recited verses from the Quran while doing a striptease which gradually revealed a suggestive outfit beneath her modest Islamic garb. A pretty forgettable routine but the entire act was filmed and posted online. Cultural meltdown ensued. She was arrested and jailed while Van Geyzel, also briefly imprisoned, was compelled to close his club for good.

Since then, he’s prospered on the global circuit and he races through his 60-minute set peppering the material with snatches of Chinese, Tamil and Malay. He seems to have picked up four or five languages without the slightest effort and his English is good enough to feature decent attempts at Cockney and Glasgow accents. Being Muslim, he discusses the Quran and the quirks of Islamic fundamentalism with an insouciant freedom that seems alien to the culture of English stand-up. If he hit the London circuit, he’d be busy every night of the week.
