Venetian director Damiano Michieletto’s new Royal Opera production of Donizetti’s Don Pasquale is a clever and entertaining mix of old and new. The curtain rises to reveal a skeleton of a 1960s style house - there are doors, but no walls, revealing a gleaming white vintage car parked outside.

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.

Maybe some British opera houses just don’t get operetta. Without wit, lightness and snappy pace, cudgelling us with desperate relevance, the frothiest works crash to earth stone cold dead. There have been disasters elsewhere, too, though ENO is the chief culprit, and (after a miserable Merry Widow and a fearful Fledermaus) this one is the nail in the coffenbach. If you think that’s a bad joke, wait til you hear the ones on stage.

Almost exactly a century after the Weimar Republic’s constitution took effect, English Touring Opera presents a show whose birth coincided with the Republic's untimely death. His third collaboration with the prolific, maverick playwright Georg Kaiser, Kurt Weill’s The Silver Lake (Der Silbersee) opened in three German cities (Leipzig, Magdeburg and Erfurt) just 19 days after Hitler had come to power in 1933.

No great innovations in this Seraglio – as ETO are styling Mozart’s early Singspiel (its full title in translation is The Abduction from the Seraglio – but a traditional staging that makes the most of all the work’s characters and quirks.

English National Opera chose a curiously low-key production to open their season. Gluck’s Orpheus and Eurydice has only three singing roles and very little action. For this production, Wayne McGregor has reimagined the work as an opera/dance hybrid.

She was recording Carmen in Paris, and the Radio France auditorium was packed with the press, asking such dazzling questions as "have you been up the Eiffel Tower yet?" and "what do you think of the French men?". I thought, given the statuesque approach, it might be best to wonder if there was a nobility in the characterisation. Jessye Norman refined it to "dignity" and enlarged graciously on that (I can no longer find the transcript or the printed feature).

Considering the doubtfulness of its underlying idea, James Macdonald’s production of Rigoletto has shown remarkable staying power since its Cardiff début 17 years ago.

Could Gerald Barry's first opera really be as enervating in the Royal Opera House's Linbury Theatre as it seemed nearly 30 years ago at its Almeida Music Festival premiere?

It was said of the Venetian audiences randy for the satirical antique of Handel's first great operatic cornucopia in 1709 that "a stranger who should have seen the manner in which they were affected, would have imagined they were all distracted".
