Dave Grohl's Godlike Genius Award from NME shortly before this gig is a definition of debased currency. For the better part of two hours after two years away, he leads Foo Fighters through a show of fearsome stamina and volume. When he says "this could take all night", like Al Jolson you believe him. But as drummer in Nirvana or leader of his own amiable band, Grohl will never surprise you no matter how long he plays. His unasked for, universal acknowledgement as the Nicest Man in Rock isn't itself a creative act.

My earliest food memory... My mum's trifle, which we used to have on a Sunday night. I do love my sweet things – as you could probably tell by looking at me! – and it holds great memories of spending time with the family. She used to make it with sliced Swiss roll and finish it off with hundreds and thousands: no trifle is complete without them.

...Featuring Norah Jones, a compilation of her duets and collaborations with other artists, is remarkable not just for the breadth of those temporary associations – which range from Herbie Hancock to Foo Fighters, OutKast to Dolly Parton – but for the way her voice holds its own in such company.

With a civilian population haunted by the Blitz and the Second World War still in the balance, it was one development Winston Churchill could have done without – an incursion into British airspace by an arrow-shaped metallic object feared to contain an invasion force of little green men.

At a time when it's widely assumed that Jack White and a handful of unknown indie chums merits the accolade, Them Crooked Vultures is a supergroup worthy of the term, in the classic rock tradition of Blind Faith and ELP.

A band picking up some "blog hype" (see below) are the young Canadian band Braids (right). Based in Montreal and comprised of two girls and two boys, the band are unsigned but have released two EPs, with talk of new material to come in the first half of next year. They play a sort of spacey, experimental pop that calls to mind Animal Collective, Broken Social Scene and Telepathe.

He is not known for his dress sense, but Boris Johnson was presented with an award by style gurus Trinny and Susannah.

Kaki King's unorthodox approach to the guitar has already secured her a guest spot on the last Foo Fighters album, and a Golden Globe nomination for her soundtrack to Into the Wild.

The Foo Fighters are one of the biggest rock bands in the world now, and I still struggle to see why. This first headlining gig at Wembley, and last album Echoes, Silence, Patience & Grace's debut in the UK charts at No 1, confirm their conquest here. But it has been a traceless rise, leaving few truly memorable songs or moments. All that lingers, as with tonight's show, is the fiercely grinning good humour and heart of Dave Grohl. The cliché that he is the nicest man in rock seems true, an honourable thing after his last band Nirvana's end. But musically, that means nothing.

'Do you mind," Dave Grohl asks several thousand Mancunians, "if we play some new shit, some old shit, some rock shit, and some acoustic shit?" That's a lot of shit. But the Foo Fighters have a lot of time. "I hope you've had a really big piss," he cautions not long after the start. "It's gonna be a long night."
