Happy returns of various kinds last night at the Wigmore Hall, where hall regulars the Brook Street Band (violins Rachel Harris and Farran Scott, cellist Tatty Theo and harpsichordist Carolyn Gibley) took to the stage along with a number of musical friends for a 20th birthday celebration concert. An all-Handel programme paid tribute to the composer whose London address gives the group its name, expanding outwards from the opening intimacy of trio sonatas and suites to finish with soprano and baritone cantata Apollo e Dafne.

The Royal Opera’s Boris Godunov production made the short trip from Covent Garden to South Ken for the company’s appearance at the 2016 Proms. The opera (here in its original 1869 version) is a good choice for concert presentation: as Antonio Pappano writes in the programme, much of its music approaches oratorio. That is particularly true of the choral numbers, and the work is a tour de force for the Royal Opera Chorus. But every aspect of the music is this production is strong, so the gains balanced the losses, despite the minimal visual presentation.

It’s impossible to get the measure of the Cheltenham Music Festival in just one day. Lasting more than a fortnight, this is the festival that made the running in postwar British music: that helped put Malcolm Arnold and Robert Simpson on the map and defined a genre - the “Cheltenham Symphony”. Times change and financial pressures increase, but under the artistic directorship of Meurig Bowen, Cheltenham is still a powerful (if undervalued) force in contemporary classical music. Of the 120-odd composers in the 2016 Festival, at least one third are alive.

The first notes of the first night of the Proms weren’t the ones expected. Instead of either “God Save the Queen” or simply the start of the Tchaikovsky, the “Marseillaise” rang out into the Royal Albert Hall, the Tricouleur projected in coloured light across the organ. Everyone stood. A fervent tribute to the tragedy of Nice, it set the tone for a strange and startlingly appropriate season opening.

Once confined to the concert hall, it’s a rare oratorio these days that doesn’t duck under the fence and sneak into the opera house. Bach’s Passions and most of Handel’s religious works have already made the transition, but this season it’s the turn of Haydn’s Creation. Rejecting the classic staged route, Garsington Opera have invited Mark Baldwin to choreograph it for his Rambert dancers. Add a trio of superb solo singers, Garsington’s own chorus and orchestra and artist Pablo Bronstein as designer, and you have an extraordinary hybrid conception.

Edward Gardner gives the downbeat, and the City of Birmingham Symphony Orchestra bursts into Verdi’s great opening guffaw. Enter stage left Graham Clark, as Dr Caius. Enter stage right Ambrogio Maestri, as Falstaff. And before a note has been sung, the audience is laughing. I know that in the post-Dumpygate era we’re not supposed to discuss a singer’s physical appearance. It’s just that everything about Maestri – his stature, his gait, his rolling eyes, his genial manner and his big rubbery smile – suggests that he was born to play the Fat Knight. He simply is Falstaff.

You know, of course, why you should always choose the left leg of a roast partridge? Because that’s the leg the bird stands on when resting: it’s plumper, tastier and altogether more succulent. These things matter, and in Jean Francaix’s extraordinary 20-minute a capella showpiece Ode à la gastronomie they’re elevated to the level of a religion. “It’s very French”, Robert Hollingworth warned us before this performance by I Fagiolini at the 2016 Lichfield Festival – and he wasn’t joking.

All the best festivals develop organically, with a guiding hand from the best directors. When I first came to the East Neuk Festival two years ago, on its 10th anniversary, it was already a special case, thriving on the spirit of place and including an all-day Schubertiad from top international artists, many of whom were returning because they loved this special peninsula of the Fife coast so much.
