While the main gallery is closed for renovation, the Wellcome Collection has taken the opportunity to mount a fascinating upstairs show exploring the way choreographer Wayne McGregor collaborates with scientists.

Here's an association test - what's next in the sequence: flamenco, gypsy, soul? Yes, you win the free tourist trip to Andalucía along with writer Elizabeth Kinder, with whom you will almost certainly enjoy weak sangria and tapas while stumbling amusingly in bad Spanish, and you won't be troubled by a single unfamiliar thought about this alluring form of dance, music and poetic song.

The Bolshoi left it till last to be most itself, to dance a ballet that is truly of its blood, its seed - its closing on Alexei Ratmansky's The Flames of Paris will leave much happiness in the memory to override the problematic productions of classics, the unidiomatic Balanchine and the awful backstage events. Here at last, in a work by the most gifted of recent Bolshoi directors, you met on stage young people who dance, who act, who love the theatre, fresh in their performing, skilled in their means, open-hearted in reaching the audience, and loved right back.

For their first visit to the UK, Shanghai Ballet have brought a narrative ballet based on a Chinese theatrical version of Jane Eyre. It focuses on Bertha Mason, Mr Rochester’s mad wife in the attic, whose fate has often troubled readers, though the Shanghai narrative does not ask about the economic and social conditions of exploitation, the colonialism and sexism that have trapped her.

The Bolshoi’s summer season in London has so far been straight-down-the-line trad: Swan Lake as an opener, Bayadère, Sleeping Beauty. Now, however, with Balanchine’s Jewels, they’ve at least dipped a pointe shoe into the 20th century, if rather cautiously.

The Bolshoi Theatre reopened in late autumn 2011 after a problematic six-year refurbishment said to have cost a tidy billion dollars, many times its original estimate thanks to corruption - it needed a corker of a ballet premiere to pop the eyes of a cynical Russian public, and it set upon a new staging of The Sleeping Beauty. This was also problematic, as three years earlier it had been promised to the then ballet director Alexei Ratmansky, who had soon afterwards resigned his job, wretched and miserable with the corrosive relationships within the theatre.

It’s unspeakably bad for so many reasons that the injured Bolshoi Ballet director Sergei Filin cannot be in London to see his company perform, and one is that he can’t see his protegée Olga Smirnova revealing herself to us as destined to be one of the great ballerinas of this era. Smirnova was signed in 2011 by Filin from the Vaganova Academy in St Petersburg, the Mariinsky’s nursery, whose combination of regal style and gossamer delicacy is evident through every fibre of this miraculous young dancer’s movement.

The mighty adorable Carlos Acosta is at the London Coliseum this week in all his might and all his adorableness - four times, you may like to know, he appears without his shirt on. This is relevant, because it’s not the preening bare-chestedness of a showbiz egomaniac like some I could name, it demonstrates the desire of a man to shed trappings, to be himself at his most unadorned, adorning the art he loves: classical ballet.

Everyone must be wishing the Bolshoi Ballet a swift return to company health after the tragic events of this year, as well as a return to physical health by their horribly injured artistic director - in the circumstances it’s heroic that they have got to London at all, let alone in such good performing order as they showed last night. Many of us will be wishing they had got themselves a worthy production of Swan Lake too, but they haven’t, and so the first night of their three-week visit to Covent Garden was not the glowing triumph it should be in the film script.

A magical folktale, a male duet, a classical jewel-box - programmes like this should be a rich part of the warp and weft of a ballet company, a night of rich interest and variety, stimulating dancers with challenges to their grace and storytelling skills. That it comes as the briefest glimpse in English National Ballet’s year is truly a pity, especially as it pays tribute to that superlative catalyst in ballet, Rudolf Nureyev.
