Rochdale boasts quite a number of star turns but those that spring readily to mind are William Walton, Andy Kershaw, Barb Jungr, Gracie Fields and Lisa Stansfield. And here’s a good pub quiz question: what, apart from Rochdale, links Gracie and Lisa? It’s their shared surname! Gracie dropped the first four letters and rearranged the remaining five. Lisa, who was born up the road in Manchester, kept it.

So it’s your birthday. Not just another one but your 70^th. So who’s on the guest list?

"The reason why it's so special to be here," says Ezra halfway through the show, "is because this is where I saw so many of my heroes". Tonight is the 26-year-old's debut at the Royal Albert Hall and the look on Ezra's face says he can't quite believe where he's standing. He holds his hands up with a shrug, stares out at the crowd, and smiles a Cheshire Cat grin.

For a few seconds last night, the Royal Albert Hall turned into London’s biggest – and cheesiest – disco. At the end of the Ball movement in the Aurora Orchestra’s dramatised version of the Symphonie Fantastique, Berlioz’s tipsily lurching waltz climaxed in a lightshow that sent a galaxy of glitterball stars swirling through the auditorium.

Blame it on the box set. The four Bach Orchestral Suites fit neatly together as a recording project. They used to fill out the four sides of a double LP back in the early stages of the baroque revival. Completists and collectors could rejoice then, and with many more versions to choose from, they still can now.

Semyon Bychkov was a surprising choice to take over the Czech Philharmonic last year, a conductor with few obvious connections to Czech music. But on the strength of this visit to the Proms, they make a good team. Bychkov communicates fluently with the players, conveying power and passion, and detail too, but without any overt theatrics at the podium.

This is the kind of thing that the Proms does well – indeed, where else would it get an outing? A "big event" piece of massive scale in terms of size and duration, in many ways a modern Spem in Alium, but where Tallis’s 1570 piece demands 40 singers, In the Name of the Earth ups the ante to 700-plus voices, led by eight conductors and arrayed around the Royal Albert Hall.

Weirdly enough, it was “Tea for Two” that definitively proved her class for me. As a second encore to Rachmaninov’s Third Piano Concerto, after a mesmeric transcription of that composer’s Vocalise, Yuja Wang’s goodbye treat channelled the mighty Art Tatum with a scrupulous respect for the jazz master’s timing and phrasing.

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.
