Do you hear the people sing? In recent months, you're more likely to have heard news stories about the longest running West End musical than the actual music. Stephen Sondheim – who celebrates his 90th birthday in March – missed the gala opening of the venue which has been renamed after him (formerly the Queen's), due to a fall – and some Les Mis singers have been pulling out as rapidly as champagne corks.

Nathalie Léger’s superbly original Exposition is a biographical novel meditating on the nature of biography itself. Its plot – if indeed its 150 pages of intense reflection bordering continuously on stream of consciousness can be called a plot – is an account of the life of Virginia Oldoïni, better known as the Countess of Castiglione.

“How many times have you heard the conductor sing?” asked William Christie after the final number, but before the two encores, of Sunday night’s 40th birthday celebration for his ensemble Les Arts Florissants. Well, lovers of old recordings know that you sometimes get plenty of impromptu vocalisation from the likes of Bernstein and Barbirolli.

There’s slight (White Christmas, to name but one) and then there’s The Boy Friend, a period musical so unabashedly vaporous that if you sneeze, it might blow away.

In one of Dora Maar’s best known images, a fashion photograph from 1935 (pictured below), a woman wearing a backless, sparkly evening gown appears to be making her way backstage through a proscenium’s drapes. The star of the show exits the limelight, cheekily concealing her face behind a six-pointed star snatched, maybe, from the star-spangled scenery.

“Chauvinism is the worst form of ignorance” is the maxim of Dr Pozzi, the hero of Julian Barnes’s latest book, The Man in the Red Coat. This historical biography follows the life of a renowned gynaecologist during the Parisian Belle Époque, the “locus classicus of peace and pleasure, with more than a flush of decadence”.

My Mother Laughs was first published in Chantal Ackerman’s native French in 2013. This year it has been translated into English for the first time, twice. Silver Press’ elegant version is framed by a foreword by the poet, Eileen Myles (who also has a poem on the back flyleaf) and an afterword by the academic, Frances Morgan. These women’s voices are sympathetic, and naturally turn the book as a whole into a kind of conversation.

This is a departure in every sense for François Ozon. The prolific French director has established himself as a master of ludic style in past dramas played out by predominantly female casts, the exceptions, among them his sad black-and-white period romance Frantz from two years ago, largely proving the rule.

This edition of Peter Culshaw’s periodic global music radio show features guest special guest Anne Pigalle. A flâneuse and doyenne of the urban demi-monde, she came to our attention recording for ZTT Records in the 1980s and ran Soho nights at the Café de Paris, did Japanese commercials for Jean-Paul Gaultier, and a series of innovative albums including Madame Sex.

While recent motor racing movies have been built around superstar names like Ayrton Senna and James Hunt, the protagonists of Le Mans ’66 (shown at London Film Festival) will be barely recognisable to a wider audience. They are Carroll Shelby, the former American racing driver turned car designer, and Ken Miles, a British driver transplanted to American sports car racing.
