His movements are minimal (perhaps they always were). A more intense flick of the baton, a sudden wider sweep of the expressive left hand, can help quicken a tempo, draw extra firepower from the players, but Bernard Haitink's conducting is still the most unforced and, well, musicianly, in the world.

So we never got the ultimate Proms spectacular, the four brass bands at the points of the Albert Hall compass for Berlioz's Grande Messe des Morts, in the composer's 150th anniversary year.

Human sacrifice has a disconcerting and wonderful effect upon great composers, above all when it involves the supremely queasy issue of a father vowing to offer up his child: think of Britten with Abraham and Isaac, Mozart with Idomeneo and Idamante, Gluck with Agamemnon and Iphigenia, and here Handel with Jephtha and Iphis in his last oratorio.

Let's be clear: this was a Prom of world-class works by English composers, not a conservative concert of English music. Politically speaking, Elgar was one of the few on the right, but how different inwardly, speaking through the poet Arthur O’Shaughnessy and singing with his own reminiscences in The Music Makers of timeless art that outlives the fall of empires and individual fates.

Can we go back to an older Glyndebourne-at-the-Proms vintage, where the chosen production was merely sketched out with variations suited to the venue, and performed in whatever evening dress might be appropriate?

After Thursday night’s concert I celebrated the Proms’ exploration of unfamiliar repertoire via the CBSO. The following evening saw the festival diving back into mainstream repertoire – as it must also do – conducted by the CBSO’s previous music director.

Puccini's and Abbé Prévost's glitter-seduced Manon Lescaut might have been inclined to linger longer in the salon of dirty old man Geronte if he'd served her up not his own madrigals but Bach's music for various harpsichords and ensemble.

Let us never tire of singing the praises of the Proms, nor ever take them for granted. For two months concerts, many of which would be the highlight of any ‘normal’ week, keep coming night after night. And for all that it is a critic’s job to comment in detail and find fault where necessary, it is also helpful sometimes to step back and say: the Proms is an astonishing festival which we should be grateful to have.

So the Proms ignored the Berlioz anniversary challenge to perform his Requiem and serve up four brass bands at the points of the Albert Hall compass.

Time was, not long ago, when the very word “premiere” was enough to ensure a sizeable smattering of red plush holes in the Royal Albert Hall audience. It seemed people did not want to risk attending new works for fear they would sound ghastly. Any artform depends for its lifeblood on strong new creations and an audience for them; so it is excellent that this concert was the second in a matter of days in which the place was packed out for a Prom including brand-new pieces.
