It’s 69 years since Went the Day Well? was released, but its moments of brutality still have the power to shock. It’s not so much the actual violence that’s shocking; when people die (and quite a lot do die), there’s precious little blood or gore, and the camera mostly shies away from the impact of knives and axes (how different on-screen death has now become, with its sploshing and spurting). What’s surprising is the steely-eyed determination with which the inhabitants of Bramley End dispatch the Germans in their midst.

There’s a lovely moment in A Midsummer Night’s Dream where Peter Quince assigns roles to his company of rude mechanicals. Unsatisfied with the part of the hero, Bottom interrupts, insisting he be allowed to play not only Pyramus but heroine Thisbe too, as well of course as the murderous lion. It’s hard not to see just a little of Bottom’s eagerness in Simon Callow’s Being Shakespeare – a one-man show penned by Jonathan Bate that casts Callow as Romeo and Juliet, Macbeth and Lear, Falstaff and Puck.

It’s the oldest coup de théâtre in the postmodernist playbook – the curtain rises to reveal an audience staring back at us – but still, in the opening seconds of Willy Decker’s Peter Grimes, one of the most effective. Our theatrical doubles here are sinister creatures indeed, massed rows of sombre Victorians whose brutal Christianity is no less severe than the angles of John Macfarlane’s set. As gazes meet across the courtroom in that moment we confront ourselves, discover ourselves in the folk of the Borough, implicated absolutely in their tragedy.

Tickets were like gold dust for this one and the stage was lit as if some of that dust had been sprinkled on the Festival Hall in a midsummer dream of a concert. The massed ranks of the Crouch End Festival Chorus, London Philharmonic Orchestra and a backing rock band magicked up on the Southbank to pay handsome tribute to the presiding Puck and genius loci Raymond Douglas Davies, alumnus of the William Grimshaw Secondary Modern School, in the manor of Muswell Hill.

It’s not often that a performance of Purcell’s King Arthur requires its entire cast of singers to strip down to very tight Union Jack boxer shorts. It’s not often either that the audience find themselves actively encouraged to talk over the music, yet both were unexpectedly and riotously true last night at the Spitalfields Festival. Pairing Baroque big-hitters The English Concert and I Fagiolini, there was nothing half-hearted about this semi-staging of Purcell’s semi-opera. It promised much and delivered more, and while those listening live on Radio 3 might have enjoyed better textural balance, they can’t have had nearly as much fun as the sell-out crowd sweltering away in Shoreditch Church.

Which came first? The low national self-esteem or the shit national football team? Is it possible, in the interests of blending in with one’s countrymen, to stimulate in oneself a love of the beautiful game? And can Britishness be boiled down to an application test? Total Football, from the two-man company Ridiculusmus, is a fleet-footed comedy which investigates the shifting parameters of what it means to belong in a country where symbols of national pride are hard to come by. Unless you count Wayne Rooney.

It'll be interesting to see what the recent race row - or more accurately, lack-of-race row - does for the ratings of Midsomer Murders. Possibly nothing, if the research that says that people from ethnic groups all hate the show and never watch it is to be believed. It certainly defies logic that producer Brian True-May has been made to walk the plank for saying that the programme has an all-white cast when... it does. Somehow, everybody has contrived not to mention this ever since Midsomer began in 1997.

At 25 years old, Jonathan Miller’s Mikado may be more Grande Dame than ingénue, but it still has a Charleston kick in its step and a shimmy in its pearls. Styled and stylised, chic and slick, it's as far from the operetta’s ubiquitous am-dram incarnations as from the Japan of the original. Yet just as the Minimalist decor and monochrome palette of an Art Deco interior prove unforgiving to the smallest hint of dust or casual clutter, so the sharp lines of this production provide little cover for the relaxed paunch or middle-aged spreadings of a revival.
