If dance lovers have learnt anything in recent months it's to take nothing for granted. How could we ever have been so blasé about The Nutcracker, whose annual reappearance in multiple productions was as inevitable as crowds on Oxford Street? As a long-departed dance critic once Eeyorishly observed, each year “brings us one Nutcracker closer to death”, a quip that now has a bleaker resonance than even he can have intended.

Theatres are currently banned from moving scenery and props about on stage and you might expect this to present a major obstacle to a production of The Seven Deadly Sins. How else is the opera’s protagonist to be seen to visit seven American cities, succumbing to a different sin in each? But Opera North’s version of Kurt Weill’s 1933 “sung ballet”, in a new translation of Bertolt Brecht’s libretto, a new orchestration for 15 players and with new choreography by director Gary Clarke, has found unlikely inspiration in the restrictions.

Unfazed by yet another forced cancellation, the Royal Ballet has notched up a small triumph over the virus. When what was to have been a performance to a live audience in the Opera House fell prey to new restrictions, it went ahead anyway.

It was a night of multiple firsts: the first live performance at Sadler's Wells in seven months (the place hasn’t been dark for so long since the War); the official first day of Carlos Acosta’s tenure as the new director of Birmingham Royal Ballet; and the premiere of his first company commission – an ambitious piece involving live orchestra, 12 dancers and a sorcerer’s handbook

"Don’t hold back,” a front-of-house manager told us. “If you want to show your appreciation, go for it.” This was nothing to do with providing sound effects for the imminent streaming to tens of thousands around the world. It was about letting the performers know there was a real, live audience in the House.

It must be tough being Michael Clark, subject of one the largest retrospectives ever dedicated to a choreographer still living. Post-punk’s poster boy is that curious thing, a creative figurehead who defined a very particular anti-establishment strand in Britain’s recent history but who is virtually unknown to today’s under-40s. Michael who? was the common reponse to my own admittedly fairly narrow survey.

So the Royal Ballet is to make a live comeback, for one night only, on 9 October. Fielding the entire company of 100 dancers, suitably distanced, the enterprise is being hailed as a triumph of logistics. And so it is. But the fact remains that the vast majority of its audience will be watching on a computer screen at home. And the gala programme will be pulled from the company’s back catalogue, health precautions having apparently ruled out the possibility of making anything new since March.

"You talk like Marlene Dietrich, you dance like Zizi Jeanmaire, your clothes are all made by Balmain, and there’s diamonds and pearls in your hair…" . Peter Sarstedt may have been a one-hit wonder, but his 1969 pop song, "Where do you go to (my lovely)?" passed into British popular culture in a flash, even if many of its chic references were lost on future generations. Zizi Jeanmaire, who died last Friday aged 96, personified the Paris of the 1940s, 1950s, 1960s, and beyond.

There’s sun and sand, and both are golden – but this is no holiday beach. Distantly, out of focus, you can make out a man with a donkey and cart. Off-camera, some locals kick a ball. A square of sand about the size of a tennis court has been carefully raked in preparation for a performance – a unique performance, as it turns out.

“That’s Marcelino Sambé, he’s wonderful,” said the artistic administrator of the Royal Ballet as I followed her down one of the many corridors that weave throughout the Royal Opera House in Covent Garden. “He’s a newly promoted Principal, a very special talent indeed!” I looked over my shoulder at the figure disappearing through some doors.
