This week Scottish Ballet opens its new season with a ballet of genius that began life in the bath. The bath is a great place for inspiration. The Greek mathematician Archimedes discovered the law of hydrostatics in it. The choreographer Frederick Ashton also had one of his major lightbulb moments while having a soak, idly listening to the radio in 1947 when a new piece of music came on.

Carlos Acosta is not just a superstar dancer with the Royal Ballet and around the world, he is an avid reader - and indeed writer. After writing his autobiography No Way Home, he has also scripted dance shows and is now writing a novel.

Bo Burnham says he doesn’t like the terms musical comic, internet sensation or teenage wonder. Well he’s all three, save the last now, as he turned 20 during this year’s Fringe - and anyway he prefers the term prodigy, he tells us in deadpan tones typical of the deeply ironic, faux offensive manner of his performance style. But sensationally talented he undoubtedly is, and this is an hour so stuffed with gags - verbal, visual and musical - that one almost doesn’t have enough time to savour each one before yet another rolls by.

What's the preferred scoff of Moulin Rouge can-can dancers? We found out, rather accidentally, last night, if you watched the final of Celebrity Masterchef. And if the world's dancers don't beat down the doors of Paris to get in, I'll eat my chat.

English National Ballet turns 60 next week, and nowadays just enduring has to be enough. Smelling of greasepaint and tour buses from the very first, it also smelled of stars - Alicia Markova and Anton Dolin who began it, Rudolf Nureyev and Natalia Makarova who created splendid productions for it, and extraordinary late-career performances by Lynn Seymour. Stars have been born in ENB too, even if they burst into full gleam elsewhere - Trinidad Sevillano, Tamara Rojo, and more than likely the young lad who is ENB’s latest find, Vadim Muntagirov, who danced last night in Cinderella.

There is a moment when you see dancers at their absolute peak that notches a bit of history in your memory - you never forget when you see it happen. In my area of contemporary choreography you can’t measure it in those terms but you can with classical ballet, and a Don Quixote performance like I saw at the Bolshoi last night sets the bar. This level of performance is Olympic-sized, it erases everything else you have seen.

In the second part of this historic career overview interview with the unique British impresarios, Victor and Lilian Hochhauser talk about their razor-edged relations with Soviet apparatchiks and the pressures they came under to prevent artist defections. Victor (who is a very engaging raconteur) reveals the lengths the Russians tried to go to stop Pierre Boulez conducting Berg in the USSR - liver-busting ceremonial vodka sessions, and a solution of Lewis Carrollian ludicrousness. "I hated them," he says, "but we needed each other."

After all the encomia for Natalia Osipova it’s time for a paean to another Bolshoi ballerina, whose witty underplaying and conquest of style makes her the lady I’d choose to see shipwrecked in full tutu, diamonds and pink satin pointe shoes on any desert island I fetched up on. Maria Alexandrova starred in two 19th-century restorations of palatial opulence - the pirate party Le Corsaire and the princess party Paquita.

Great stars get lost sometimes. Up there in outer space, ringed with adulation, when they get a mid-life crisis sometimes they get sucked into a vanity black hole. No light emits, just the tatters of an angel who lost his way in his own legend.

When the words "commercial" and "art" come together - as they do with the Bolshoi season currently at the Royal Opera House - odds are the glue between them is a three-word phrase "Victor Hochhauser presents". Victor and Lilian Hochhauser are the impresarios behind most Russian ballet seasons UK-wide, and they have a reputation for solid box-office commercial taste, which is easily dismissed as the safe option. But they are in their eighties now, and conservatism is forgivable.
