It stunned me to discover that last night was only the sixth time Carmina Burana had been heard at the Proms. It seems tailor-made for the festival: large-scale and bombastic in a way that fits the proportions of the Albert Hall, familiar to occasional concert-goers but with much more to it than the "famous bit". And in this performance the CBSO and an array of choirs went at it with gusto, raising the audience to its feet at the end.

Perhaps music and politics should always stay at a decent arm’s length; in the modern world, they seldom can. The Hallé’s annual visit to the Proms presented an all-Russian bill and closed with Shostakovich’s Fifth Symphony: his much-disputed “Soviet artist’s response to just criticism” and a classic instance of the collision between art and power as, in 1937, the composer struggled to survive Stalin’s potentially fatal disapproval.

One of the undoubted highlights of Prom 14 was unprogrammed – following his commanding performance of Beethoven’s third piano concerto, Jan Lisiecki returned to the stage to give an encore of Chopin’s Nocturne in E Flat, Opus 9 No 2.

A full house, and television cameras: rarer events at the Proms than they used to be (or should be). Both lent a sense of occasion to the BBC National Orchestra of Wales’s visit to the Royal Albert Hall with their Conductor Laureate, Tadaaki Otaka. The cameras (for a BBC Four broadcast on Friday) had descended not for Cardiff’s long-serving Japanese stalwart – who first led BBC NOW in 1987 – but for Elena Urioste’s performance of the Violin Concerto by Samuel Coleridge-Taylor.

This Prom by the BBC Philharmonic was billed as a celebration of the 50^th anniversary of the Royal Northern College of Music, in distant Manchester.

Even before the Just Stop Oil protesters hit the stage after the interval, this was destined to be one of the most politically charged Proms the Royal Albert Hall has witnessed for a while. The rousing cheer that greeted the BBC Singers was hopefully all the beleaguered BBC bosses needed to realise – after the ill-advised attempt to abolish them in March – what a key part of our music culture they remain today.

The recently re-branded National Youth Choir was founded in 1983 as a single choir of about 100 voices, and in those 40 years has grown to be a family of four, ranging from the nine-year-olds at the bottom of the boys’ and girls’ choirs to the 25-year-olds at the top of the NYC proper.

Flying manes and flashing eyes are part of the inspirational package. We may laugh at some of these dramatic images, but it's usually a sign of the conductor's commitment to his or her orchestra and audience. There's no doubt that the Royal Albert Hall from July to September is a place where magic can happen, even if it's as unpredictable as the acoustics of the capricious venue itself.

So John Eliot Gardiner’s fire- and-air way with Beethoven’s Missa Solemnis turned out to be the last night of the Proms. Just as I was about to cycle to the Royal Albert Hall for the first of the Philadelphia Orchestra’s two Proms the following evening, a notice came through: following the news of the Queen’s death at 6pm, the evening’s event had been cancelled.

Back in 1990, John Eliot Gardiner with his Monteverdi Choir, English Baroque Soloists and world-class singers set the South Bank alight with revelatory concert performances of Mozart’s Idomeneo and La clemenza di Tito. Now he's done it again for an even quirkier masterpiece, burning away any Albert Hall mists with the best possible voices and an “Orchestre” which can be called “Révolutionnaire” but decidedly not “Romantique” when it comes to the Missa Solemnis.
