Revivals, especially at Covent Garden, too often wrong-foot high expectations.

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.

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.

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.

My great-grandmother used to say, "In the fall, leaves fall," meaning that as the weather gets colder, people die. The Royal Ballet has had leaves falling all year, and in the height of the (ha!) summer one of the most tenacious, and most beautiful, finally fluttered down. Leanne Benjamin, a principal since 1993, retired in the role of her choosing, Kenneth MacMillan’s Mary Vetsera, a crazed, sexed-up nymphet with a death-wish.

Ballet is telling stories again. Last night Wayne McGregor’s debut as a narrator followed hot on the heels of Cathy Marston’s Witch-Hunt for Bern Ballett, both in the Royal Opera House complex, and Northern Ballet’s visit to London with David Nixon’s new The Great Gatsby. (To say nothing of David Bintley's Aladdin and even less of Peter Schaufuss's Midnight Express.)

"Oh, wretched old man! You are but the shadow of the king”, sings Plácido Domingo’s Nebuchadnezzar about himself in Lear-like abjection before his Goneril-Reganish daughter (the flame-throwing Liudmyla Monastyrska). It’s only true of this brief phase in the protagonist’s sketchy operatic trajectory from hubris brought low to piety raised on high.

Colin was an enormous influence in my youth and I’d like to share some memories of those days. It was over 60 years ago, on a Sunday afternoon in May 1952, that  I attended a concert performance of The Marriage of Figaro given by Chelsea Opera Group in a school hall in Hills Road, Cambridge. The singers were all young, gifted and sparky. The orchestra purred. The narration (written by David Cairns) was genuinely funny, indeed it seemed bliss to be alive that afternoon and to be young (I was 21) seventh heaven.

General booking for the Bolshoi Ballet's Covent Garden season this summer opens on Tuesday (9 April), and the company has at last announced its intended casting. However, it should always be borne in mind that, as Les Ballets Trockadero de Monte Carlo habitually announce before every performance, "in accordance with strict Russian tradition, there may be changes".
