It's 20 years since the death, backstage at the Royal Opera House, Covent Garden, of a man who scripted high-wire emotions and extreme psychological states in a theatrical language that had widely been held to be the realm of sweetness and majesty. The choreographer Kenneth MacMillan brought the values of modern theatre, cinema and the sexual revolution to ballet, and his narrative daring remains unequalled by any choreographer in Britain after him.

Hans Werner Henze, the composer who died on Saturday aged 86, wrote the music for one of Margot Fonteyn's signature ballets, Ondine, a ballet about an inhuman spirit who longs to be joined to a man - but when she does, he must die. It might almost be a metaphor for the death of the thought the moment it is realised.

Rio Ferdinand did four years' ballet training as a child, England manager Graham Taylor sent the national squad to dance classes, while the Royal Ballet once ran an active football team. Ballet and football have long been secret lovers backstage. But they have only been rarely seen out together in public.

Faster, higher, stronger - and more graceful. There is a handful of top athletes and sportspeople who are the beautiful people, who have some divine extra dimension to their movement that makes you smile to see them. They're winners, but they're seraphic dancers too, and they make all the other winners look tough and effortful.

How many classical ballet dancing jobs, full-time, are there in Great Britain? I make it just 289. That's the Royal Ballet 94, English National Ballet 67, Birmingham Royal Ballet 57, Scottish Ballet 36, Northern Ballet 35. Rambert does sometimes take classically trained dancers: another 23. So, at a stretch, 312 full-time jobs for Britain's classical ballet graduates to be searching for a vacancy in. Moreover, a profession in which most are tenacious of their jobs, staying perhaps 10-plus years.

Two hundred years ago in Durham taverns you could find men in wooden clogs clattering on the tables, with their mates pressing their ears to the underside of the surface. Meanwhile, at the other end of the world, African slaves with bare feet were shuffling on dirt with metal bottle caps held between their toes. Now picture a Mediterranean gypsy dancing of sorrow and pain with swirling shawls and angrily pounding heels. Three quite different scenes, different places, different eras, but all rooted in one human impulse, common the world over.
