Irish soprano Jennifer Davis, a stunning Elsa in this Royal Opera season's revival of Wagner’s Lohengrin, was the lure to sit through Jan Philipp Gloger's Mozart Così again (the title, by the way – "All Women Do It" – belies the complexity applied to a schematic plot). As it turned out, the mixed-up couples were all love’s young dream, which made it all the more of a shame that this production remains determined to squash their hopes and even their new matches.

Words and situations are one-dimensional, but the music is chameleonic, if not profound, and crafted with a master’s hand. What to do about Saint-Saëns’s Biblical hokum? In Richard Jones’s new production, the end justifies the means, with persecuted Hebrews and mocking Philistines circling two essential star turns, and Antonio Pappano’s handling of a hard-to-pace score is vivid from opening keenings to final cataclysm.

It has been a difficult couple of years for us in the world of opera, losing several of our most respected and admired colleagues who have inspired us over several decades.

David Alden’s Lohengrin is back at Covent Garden for a first revival. The defining image the first time round, in 2018, was of the ending, a political rally for King Henry’s regime, with Lohengrin and the swan as its icons. That felt crude – a two-dimensional morality, and tangential to the story.

"Why does he have to sentimentalise this piece?", Britten is reported by former Royal Opera director John Tooley to have said of Jon Vickers as Peter Grimes the tormented fisherman, so very different from the composer's life partner and creator of the role Peter Pears. Britten didn't qualify his disappointment by stating what for most of us is obvious: Vickers was one of the great tenor voices, and his latest successor in the role, Allan Clayton, is heading for that kind of status too.

Two Royal Opera staples, Verdi's La traviata and Puccini’s Tosca, now come round with too much frequency for critical coverage. It looks like Director of Opera Oliver Mears’ Rigoletto will do the same. Yet the production’s September 2021 debut was clouded by routine performances from its protagonist baritone and tenor Duke of Mantua, so a second visit was due to see if fresh casting might make a difference.

One of the galvanizing wonders of the operatic world happened when David McVicar’s production of Mozart’s The Marriage of Figaro was new, back in 2006: the sight and sound of Royal Opera music director Antonio Pappano in seamless dual role as conductor and recitative fortepianist.

Phyllida Lloyd’s production of Macbeth has been in rep at the Royal Opera since 2002, and it is a solid performer. The setting is slick and vaguely period, with lots of iron weaponry, smart, pony-tailed warriors, but not a kilt in sight. The set (designer Anthony Ward) is a foreshortened metallic box, from which the back often rises to reveal a stormy sky (for the witches) or to introduce large scale props.

Few musicians get to stage-manage a dignified departure from the world.

“I want to tell her that people will be good,” Tewodros Aregawe of Phosphoros Theatre confided to us as Little Amal closed her eyes on the giant bed made up for her in the Paul Hamlyn Hall, “that all the people with kind eyes who have walked alongside her and listened to her story will be louder than those who wish she wasn’t there”.
