There’s a line in the late Richard Greenberg’s 2013 play that refers to a recently elected showbiz type turned politician who sports puffed up hair – but it’s not the current incumbent of what’s left of the White House but Ronald Reagan. 

The problem with making TV dramas about unsolved real-life murder mysteries is that they’re still unsolved, unless the film-makers decide to invent a fictional denouement. This might well trigger an avalanche of legal and ethical objections.

A curious mind, indeed. Outer space, and what may be there. Communicating with those in the hereafter. Spooks, vampires and other horror film perennials. The wild west. Deceased rock ’n’ rollers Eddie Cochran and Buddy Holly.

As the Poppies’ set at Birmingham’s O2 Academy drew to an end on Friday night, co-vocalist Mary Byker barked into his microphone: “Reform is on the rise? Why is that? We shouldn’t be singing this song anymore”. The song in question had their home crowd pogoing like lunatics and howling back at the stage, “Ich bin ein Auslander auch!” at the top of their lungs.

The Scottish Chamber Orchestra punches well above its weight when it comes to guest artists, and it was a big thing for them to have someone of the status of Alina Ibragimova as both soloist and guest director for this concert.

I came late to the Old Vic's shimmering production of Mary Page Marlowe, Tracy Letts's Off Broadway play from 2018 which has arrived in London with Andrea Riseborough and Susan Sarandon leading a sizable and uniformly excellent cast. And I hope theatregoers will catch this too-short run while they can. Amidst ongoing chat – sometimes justified – about screen stars not being able to hold their own stage, Matthew Warchus's keenly attuned staging proves that just as often they very much can.

Niall is unwell. Very unwell. Very, very. There’s a lot going on in his head. He can’t really hold things together. Evidence? Well, he’s lost his job and his girlfriend Natalie has left him. So, as desperation increases, he decides to phone his big sister Brigid – the trouble is, it’s 3 o’clock in the morning.
