This does mean there’s space for the excellent Abigail’s Party to transfer from the Menier Chocolate Factory, where it had a sold out run, to the larger Wyndham’s Theatre. Starring Jill Halfpenny, Joe Absolom and Natalie Casey (who’s hilarious), this is a brilliant new version of Mike Leigh’s classic comedy and should continue to make audiences cringe and chortle in equal measure now it’s in the West End.

Other new shows heading to London in the coming weeks are Six Actors In Search Of A Director, a new comedy written and directed by Steven Berkoff at the Charing Cross Theatre from 16 May; and Democracy, Sheffield Theatre’s critically acclaimed production of Michael Frayn’s 2003 hit, at the Old Vic from 15 June.

Finally, have you ever fancied yourself as one of The Beatles? New West End theatrical concert, Let It Be, is running open auditions to find actor-musicians to play the fab four. Head to the Gielgud Theatre on 8 May to show off your talents; successful applicants will join the cast of Let It Be when it opens at the Prince of Wales Theatre in September this year.

The Queen attended the comedy show with Prince Philip, their grandson Peter Phillips and his wife Autumn. She avoided attracting attention from the royal box, instead entered the foyer unannounced shortly before curtain up and sat among the rest of the audience, many of whom reportedly saw our monarch “giggling through the performance”, according to the Official London Theatre website. I’m so pleased she’s been able to see this show: I’ve been recommending it to everyone I know for ages! It’s a real hit, and I’m sure her Majesty thought the same.

And I bring news of an extension at the Royal Court: In Basildon has received rave reviews, and will now play until 5 April. The story of a working-class man on his death bed, In Basildon explores the complications of inheritance and the myth of place. It’s directed by Dominic Cooke, and stars Linda Bassett, who is known for her TV appearances in Larkrise To Candleford and Grandma’s House.

Next up, a new solo show at the Trafalgar Studios. Chris Larner’s award-winning An Instinct For Kindness plays at the Trafalgar Studios for three weeks this spring. The play takes on the contentious topic of assisted suicide, telling the story of Larner’s 2010 journey to the Switzerland Dignitas clinic with his chronically ill ex-wife. The Fringe First Award-winning show plays from 10 April to 28 April, following a critically acclaimed run at the 2011 Edinburgh Fringe Festival. The Independent described An Instinct For Kindness as, “Intensely moving, at times overwhelming”.
