A much tinkered-with show needs to go back to the drawing board, if this latest iteration of Strictly Ballroom: The Musical is any gauge.

A one-time Martha and Maggie the Cat in the theatre, and a screen siren of the sort they don't make any more, might not be the first person you expect to see swaggering on to a London stage in a dark pantsuit ready to offer up two hours of song and chat.

Conflict and comedy can be unpredictable bedfellows, and Chicago playwright Joel Drake Johnson’s 2014 play occasionally risks overstretching itself in its attempts to reconcile the two – although its immediate context, the world of office politics, has a rich history of showing humanity at its worst, and such ghastliness can be painfully funny.

Back by feverishly popular demand, Jim Steinman’s mega-musical is no longer in danger of alarming unsuspecting opera-goers. A year on from its Coliseum debut, this indisputably bonkers show moves to the West End venue it was surely always destined for – that lingeringly inhabited by its rock operatic forebear.

It is, perhaps, a tale that suffers from overfamiliarity. Tina Turner’s rags-to-riches story – from humble beginnings as little Anna Mae Bullock in Nutbush, Tennessee, to her discovery, reinvention and sickening abuse by husband and manager Ike Turner, and finally her rebirth as a solo rock'n'roll star – is the stuff of showbiz legend.

There’s a whole universe which British theatre has yet to explore properly – it’s called the sci-fi imagination. Although this place is familiar from countless films and television series, it is more or less a stranger to our stages.

"What could be more serious than married life?" asked Richard Strauss, whose operas became a surprising pillar of Glyndebourne's repertoire some time after the early days dramatised in David Hare's play. "Honour" might have been the answer of conductor Fritz Busch, who unlike Strauss never made accommodations with the Nazi regime.

Chicago has been on, in one form or another, for a very long time.

You could be forgiven for not remembering the “coughing major” brouhaha in 2001, coming as it did the day before 9/11, when we had rather more pressing matters to attend to than a contestant being accused of cheating on television quiz show. But playwright James Graham has mined an entertaining confection from the affair and its subsequent court case in 2003.

Even in its successful early days Wycherley’s 1675 comedy was notorious, but it was considered too lewd to be staged at all between the mid-Eighteenth Century and 1924. Although the play has found an affectionate place in the canon in more recent times, it makes a kind of sense to transpose the goings on of louche Restoration aristocrats to the era of the Bright Young Things, the time of its rediscovery.
