When I last met Nitin Sawhney, I’d heard that he was a whizz at mental arithmetic. I asked him, perhaps impertinently, what was 91 times 94? “8,827,” he relied, quick as a flash. Several hours later, I worked out he was probably right. “Vedic mathematics,” he said. What I can say about last night’s performance was there was some interesting mathematics going on. Some time signatures rubbed friskily against others in certain scenes in ways a mathematician would love. The score had an enormous facility.

Tucked away down a sleepy residential back alley in suburban Tokyo, Studio Ghibli, the headquarters of Hayao Miyazaki, is designed - by the visionary animator himself - in the shape of a boat. When I visited it five years ago, just before the release of his last film, Howl's Moving Castle, the team of young animators all had bowls of fish and terrapins on their desks. The result, Ponyo, is at last about to open in Britain: Miyazaki is a famously slow worker, and the delay has been compounded by a hold-up with distribution. But this irresistible marine fairy-tale is worth the wait.

When Carlos Acosta danced Spartacus with the Bolshoi Ballet in London in 2007, the man, the time and the place united the strands of a most extraordinary story in ballet, a story of peregrination, of dreadful reverses, of the pursuit of civilisation, of holding on to the best of human values in despairing times.
