Instant sell-out would have been guaranteed if the Royal Opera had advertised this as “Cardiff Singer of the World finalist Masabane and fellow Young Artists”. No doubt about it, South African soprano Masabane Cecilia Rangwanasha is indeed the most polished performer, crying out star quality in every move and note. But that’s not the point.

They showed Clash of the Titans the other night – not the wretched remake, but the original 1981 sword-and-sandals cheesefest, complete with Ray Harryhausen’s Kraken, Ursula Andress as Aphrodite and that rip-roaring Laurence Rosenthal score. And, of course, Sir Laurence Olivier playing Zeus and keeping it old school as he and his nightdress-clad fellow deities debate mortal destinies in Shakespearean tones, from an Olympus that resembles nothing so much as the old Blue Peter set plus Ionic columns.

“If this is love, then why have I fought it?” The stock romantic-comedy prevarications had a Greenwich Village setting in Bernstein’s Wonderful Town at Opera Holland Park less than two weeks ago. Last night, the place was nominally Alsace but the style totally Italianate.

Harnessing the enthusiasm of youth has always been what Clonter Opera, on a farm in Cheshire, is about with its summer productions. The house is relatively small (there’s always a reduced orchestration as accompaniment), and the idea is that promising young voices can get a chance to try their luck with an audience and learn in the process.

Gorgeous woodland romp, a tale of a vivacious, independent-minded young lady-into-fox objectified by three ageing, disillusioned men or a parable of natural regeneration? The different levels of Janáček’s one-off fantasy, from strip-cartoon origins to wise philosophy, are hard to hold in balance. Director Stephen Barlow sketches the possibilities but no more,  meeting many of the veteran composer’s seething orchestral passages with a dramatic blank.

“Remember me!”, sang Dido to a departed Aeneas in the heart-rending aria-chaconne announcing her demise that dominates the ending of Purcell’s baroque opera. But what if he did … if in fact he never could forget her?

How would you solve the problems inherent in a production of Malcolm Arnold’s The Dancing Master, bearing in mind the need for social distancing for performers, comparatively miniscule budgets for scenery and props, and the uncertainty surrounding just about everything in a summer opera festival these days?

When the history of 2021’s slow emergence from lockdown comes to be written, musical administrations will stand out among the heroes. That’s especially true of the country-house opera organisations which have mushroomed in recent years. Don’t ask where some of the money comes from, or who it’s for, but celebrate for now how much work these set-ups have given top-notch singers, players and production teams, many of whom have hardly worked in the previous 14 months.

In Handel’s operas (as, indeed, elsewhere in art and life) the worst witch may turn out to have the best character. Without the sorceress Melissa, splendidly full of evil ruses yet endowed with a generous measure of tragic pathos, Amadigi di Gaula might freeze into a static amorous stand-off between pasteboard nobles contending with a harsh – then, suddenly, kindly – fate.

A massive musical hope for the future is what we all need right now, after 14 stop/semi-start months and a threatened decimation of the concert and opera scene, the danger of which isn't over yet. This year’s BBC Cardiff Singer of the World delivered that hope in frissons and plenty of tear-inducing moments, even though the live audience in St David’s Hall consisted of only three empathetic judges.
