This is great news. It should have been great news back in 2006-7, when Wigglesworth – Mark, not to be confused with the young, photogenic Ryan, composer and, when I last saw him, barely competent baton-wielder - was among the contenders for the post of Music Director at English National Opera. As it happened, the then relatively unknown Edward Gardner sailed into the job with precocious assurance and versatility.

Massenet had just two lingering thoughts about Manon when he wrote his memoirs in 1910, a quarter-century after the opera's first performance. First, he enjoyed reminding himself how many times it had been performed (a staggering 763 by the time he finished the memoirs). He also stressed that the choice of the singer to play Manon herself was crucial, needing an "artist who suited this role just as I wanted, and who could represent perfidious and dear Manon with all the heart that I had placed in her," with the right "qualities of vocal seduction".

It has to be partial, because out of the 10 opera productions from the iconoclastic French actor-director, who died yesterday of lung cancer at the age of 68, I’ve seen but two, on screen only – but a big two at that – and only three of his 11 films. Yet they all had a tremendous impact, one way or another.

Rich, racy, randy and irreverent: such were the R words gathered up by a Canadian critic to capture the essence of Christopher Alden’s production of Johann Strauss’s cork-popping operetta when it premiered in Toronto last year. Other R words, alas, came to my mind, like rubbish, reprehensible, risible, even rigor mortis.

 A lot has changed in the 10 years since Serge Dorny arrived at Lyon Opera. Attendance in a supposedly dying art form has risen to 96 per cent, and no charges of elitism or unfashionable nostalgia have deterred the 25 per cent of Lyon’s audiences who are now under 26 – Europe’s youngest opera-going crowd. But how has Dorny managed this, and at what cost? Is he really the Opera Whisperer or are his innovations just gimmickry, shiny bandages temporarily plugging a fatal wound?

Her tongue firmly planted in her cheek, Mariame Clément grumbles in the Glyndebourne programme that Don Pasquale “poses no specific ‘conceptual’ challenge” to the opera director. Sighs of relief all round. Donizetti’s final comic masterpiece turns out to be “about” nothing but its own subtly nuanced retelling of the stock tale of the old buffer who plans to marry his ward, nephew’s sweetheart, or some such, but is outwitted by her with the help of a smart confederate.

“I do not believe in miracles,” scoffs Herodias in Oscar Wilde’s -  and Richard Strauss’s - Salome. “I have seen too many.” I know how she feels. So it was a bit of a shock to find the highest-kicking of today’s composers, John Adams, and his inseparable genius director Peter Sellars, taking the raising of Lazarus seriously in the first part of their latest opera-oratorio (my term, not theirs, and also applicable to El Niño, Adams’s millennial take on Christ’s birth and its concomitant hazards).

There is only one rule by which one should ever judge a Barber of Seville. If your eyes (and possibly also your trouser legs) aren’t moist by the time the interval arrives, you might as well leave. The last time this Jonathan Miller production was revived by the English National Opera, it passed with flying colours. This time round, I was dry as a bone. Three hours and I notched up two smiles and a snigger.

After what must seem like a long exile, the opera director with one of the most distinctive track records in the business is to return as chief executive of a company which has been on fitful form recently. As, it must be said, has Pountney's recent history after the celebrated "powerhouse" era at English National Opera alongside Mark Elder and Peter Jonas. Since then, he has veered from the trademark business verging on chaos to a tender, painstaking rediscovery of recent works which deserve our attention.

The Royal Opera has announced that Kasper Holten, artistic director of the Royal Danish Opera, has been appointed Director of Opera at Covent Garden, to succeed Elaine Padmore at the end of this season.
