The Sleeping Beauty was the ballet that kissed the then Sadler’s Wells Ballet into stardom in 1946; after a string of poorly conceived Beauty productions, today’s Royal Ballet hurtled back 60 years in 2006 to try to recapture some of that historic Forties magic in its current staging of this most awesome and enchanting of the classical ballets. A half-cock production resulted with an unlikely liaison of sherbert-chiffon new costumes inside picturesque Oliver Messel period sets.

Those of us un-Zeitgeisty enough to miss the Royal Ballet’s first new full-length ballet in 20 years during its first run can now catch up. Opus Arte’s DVD release of the televised Alice’s Adventures in Wonderland tells a different story from the one any audience members other than front-of-stalls ticket holders would have caught. With more focus on the characters and less on the potentially overwhelming special effects, we probably get a better deal.

The cool physical activity of McGregor’s Limen, the crimson passions of Ashton’s Marguerite and Armand, the symbolic sculpture of MacMillan’s Requiem - the weekend's new triple bill at Covent Garden shows three faces of British ballet-making over the past half-century. While none is the masterpiece of its creator, together they describe an arc over time where lyrical emotion became replaced by gymnastic motion, compression by diffusion, individual idiosyncrasy by a kind of balletic collective.

Death concentrates the mind wonderfully, as they say. In the wake of the demise last week of Alexander Grant, who owned the choreographer Frederick Ashton's world-wide hit ballet La fille mal gardée, the Royal Ballet has announced that it is launching a foundation to "perpetuate the legacy and work" of the distinguished choreographer 23 years after his death.

You hear the names of the princes and romantic heroines in ballet, but the global success of 20th-century British ballet had much to do with its dramatic acuity and nuancing, the unexpected side characters who in the ballets of Ashton and MacMillan were vastly more interesting than the stock supporting roles of 19th-century ballet. Alexander Grant was the key man in the growth of sophistication in British ballet in the Forties and Fifties, a character performer of powerful personality, and a performer who could out-dance almost any leading man.

The star ballerina Sylvie Guillem was rehearsing in London when she heard about the cataclysmic Japanese earthquake last spring, and the devastating tsunami in its aftermath. It was an apocalyptic blow that she felt personally. Since her first visit there as a teenager, the internationally renowned dancer has been drawn back to Japan year after year, winning legions of friends and supporters, the culture’s aesthetic clarity and spareness influencing her taste, and complementing her own evolution from classical ballerina assoluta into contemporary dancer stupenda.

On six more occasions you can have an ideal experience of dance by visiting the Degas exhibition at the Royal Academy and then going to see Balanchine’s Jewels at the Opera House.

“What I love about her is her emotion, her true emotion. She’s a ball of energy and emotion all together, quite an amazing thing. From the first time I saw her, I thought I want her to be my girlfriend.” Ivan Vasiliev, the young Bolshoi Ballet superstar, is talking about his girlfriend - though he could also be Romeo talking about Juliet.

Roland Petit died this morning aged 87, a world choreographer of chic and erotic theatricality who blew away the French classical ideal in a roar of post-war sexual liberation. He created an all-male corps of swans for Swan Lake long before Matthew Bourne, and his roles for his exquisite wife, Zizi Jeanmaire, repositioned ballet drama upon the femme fatale rather than the virgin. Arguably, though, for British ballet-goers he was above all the seducer who almost lured Margot Fonteyn away to France (and who got her to have a nose job) just as she was leading the Sadler’s Wells Ballet to international glory. Had Fonteyn done so, the history of Britain’s ballet would have been different.

Last weekend ballerina Tamara Rojo performed to the largest live audience ever to watch the Royal Ballet, at London's O2 Arena. But what was it like facing 12,000 people, and trying with her partner, the Cuban star Carlos Acosta, to tell the intimate story of two young lovers in Kenneth MacMillan's Romeo and Juliet? She tells us it's a weirdly out-of-touch experience on that vast stage, almost like being in private. And thank goodness for the cameras.
