In September 1899, Claude Monet booked into a room at the Savoy Hotel. From there he had a good view of Waterloo Bridge and the south bank beyond. Setting up his easel on a balcony, he began a series of paintings of the river and the buildings on its banks. So entranced was he by the river that, over the next three years, he came back twice to continue working on a series that would mushroom to over 100 canvases.

If Angela Hewitt’s recital last night at the Wigmore Hall was a meal, it would have been two light, fresh – but nourishing – courses, followed by a big suetty pudding, splendidly cooked but sitting slightly heavy on the stomach.

Michael Craig-Martin was the most playful and provocative of the conceptual artists. His early sculptures are like visual puns, a play on the laws of nature. On the Table, 1970 (pictured below right), for instance, appears to defy gravity. Four buckets filled with water stand on a table; so far so ordinary. But the table has no legs and is suspended from the ceiling by ropes and pulleys.

Iconic is a word the meaning of which is moving from the religious world into popular culture – win a reality TV show dressed as a teapot, and you can be sure that your 15 minutes of fame will be labelled iconic across social media. Not quite what Andrei Rublev had in mind 600 years ago.

We meet Joe first at the keys, singing a pretty good song, but we can hear the pain in the voice – but is that the person or the performance? When Ellie walks in, he leaps up like a cat on a hot tin roof, nervous as a kitten, and we know – it was the person.

The setting is the lively 1930s London theatre world, but any sense that The Critic will be a lighthearted thriller should soon be dispelled by a soundtrack featuring “Midnight and the Stars and You,” the song that Stanley Kubrick used to ominous effect in The Shining.

One wonders what sitcom writers will do when supermarkets finally sweep the last corner shops away with nobody left old enough to buy cigarettes, nobody so offline that they buy newspapers and nobody eating sweets, priced out by sugar taxes. The convenience shop is already acquiring a patina of nostalgia, crowned by a warm glow of happier days. My mother used to send me out aged seven to buy her Embassy Number 1s with me levying a charge of one gobstopper in payment - see, I’m a victim already.

Platonic love should be simple – basically you’re best mates. And without the complications of sex, what could go wrong? Waleed Akhtar, whose big hit The P Word was also performed here at the Bush, takes this idea and complicates it – by making it about a gay boy and a straight girl.

Going to the theatre can be a little like going to church. One communes on the individual level, one’s faith in the stories underpinned by a psychological connection, but also on the collective level, belief rising on a tide of shared emotions. Those complementary sensations, in an ever more individualised, screen-and-earplugs world, are rare – and an example of why people pay big bucks for Glastonbury, Taylor Swift and Oasis.

“I’d know her. Bone of my bone, flesh of my flesh. Would I know her? Would I?” John (a brilliant Jared Harris, who’s also an executive producer) is always looking for his daughter, who ran away from home ten years ago at the age of 14 and hasn’t been seen since.
