Botticelli is a household name, but who knows the true story behind his most famous painting? The painter's 1480s masterpiece, The Birth of Venus, is one of the most striking images of Renaissance Florence – and has achieved iconic status. Because it has been minutely dissected by generations of art historians, it takes a bold playwright to smash through the scholarship and give a memorably fresh, in not necessarily accurate, account of its commissioning. Enter Jordan Tannahill, the Canadian polymath whose work spans theatre, film, dance, novels and everything else.

Considering that Janáček’s Vixen is, among other things, an allegory of the passing and returning years, it’s appropriate that WNO continue to recycle David Pountney’s now nearly 40-year-old production, and that it comes up each time refreshed, with this or that altered or added detail, but quantum-like the same general image. This second night was like a mass family outing, perhaps because of the associated outreach event, the designs for which adorned the foyer.

One question springs immediately to mind on hearing that Romesh Ranganathan’s new stand-up show, The Cynic’s Mixtape, is touring: how does he find the time? Ranganathan has overtaken Jack Whitehall as Britain’s most media ubiquitous comic, with a deluge of TV shows and appearances, a column in the Guardian newspaper and even a recent autobiography. However, his TV CV is hit’n’miss, which leads to a second question: can he still cut it in the live arena?

Swedish singer Tove Lo appeared at a time when female physical sexuality was being used as a raw, blunt weapon in pop, when porno chic reached an apex in music videos. Half a decade ago was the time of Nicki Minaj’s “Anaconda” and Miley Cyrus’s “Wrecking Ball”, thus Lo’s overt displays of sexual bravado seemed part of the same and she had big hits with songs such as “Habits (Stay High)” and “Talking Body”.  Her output since, however, has proved her sensual agenda to be more than a passing foible.

Described as a "performer-led re-devising’"of Mozart’s 1787 opera Don Giovanni - a tale of an arrogant and ruthless lothario who seduced countess women - Don Jo certainly played around with many of the norms we encounter in both sexual relationships and in the operatic genre.

William Finn and James Lapine’s musical – which combines two linked one-acts, March of the Falsettos and Falsettoland, set in late 1970s/early 1980s New York – picked up Tony Awards in 1992 for its book and score, and was nominated again in 2

We're saying goodbye to a much treasured friend. Fleabag will live on, of course – other actresses have and will inhabit the role – but Phoebe Waller-Bridge, its creator, has said this short run at Wyndham's Theatre is the last time she will perform the character on stage.

Jeanne – employment, age and appearance unknown, motives unknowable – is building a collection of penises. In street after street, she feigns dizziness; on the inevitable approach of a man eager to lend his help, she leads him to a hotel room. After the encounter, she does not retain any recollection of this man’s face, body or name; in the intricate interior of her memory palace, only the textured details of the penis, the "shape, the form, the particular warmth, the density, the smell", are carefully preserved.

Being a teenager used to be fun, allegedly, but for the young cast of HBO’s controversial new hit series Euphoria it looks more like a nightmare ride through a theme park of bad trips.
