"It's the second time we've played at the Concorde," says Delays frontman Greg Gilbert. He adds something about how glad they are to be back, but you can't help feeling that the Southampton quartet think that they should be headlining some vast sports arena by now, performing their anthemic songs as untold multitudes punch the air. As they launch into Long Time Coming - equal parts New Order and U2 - a chubby bloke near the front gets on his friend's shoulders and waves his arms about. It's a start, but it's hardly 80,000 people simultaneously hoisting their lighters aloft in the gathering dusk.
The Delays certainly act as if they were somewhere much larger. At one point, keyboardist Aaron Gilbert leaps from behind his bank of synthesizers, sticks his finger in his ear and pulls a face. The significance of this display is difficult to pin down, but in his head, at least, he is clearly being beamed on to giant video screens either side of the stage.
So why isn't he? It's easy to feel as mystified as the band: Lost in a Melody is so ridiculously commercial, so laden with hooks, that it's hard to believe it wasn't number one. The prosaic answer may be that Radio 1 is bewilderingly indifferent, but it's also true that occasionally, the icy synth lines tip into portentousness, the vocals become a bit overwrought and it sounds like the sort of thing that, 20 years ago, would have been accompanied by a video of the band performing stern-faced before billowing white curtains.
But can you blame them for trying too hard? They play recent single Valentine, a song that makes Lost in a Melody sound like Einstürzende Neubauten, but which stalled at number 23. The stadiums seem frustratingly out of reach, but the crowd in the more bijou confines of the Concorde, at least, are delirious.
