THE CUT-OFF point at which ‘the past’ is deemed too recent to evoke nostalgia appears to have shifted. These days, pop songs from 2000 make the playlist of radio’s ‘golden olhe’ hours. And retrospective television shows run archive footage from the late Nineties. Where will it end? Or perhaps I am just being nostalgic for a time when the objects of our nostalgia were, well, less modern – complaining, in effect, that nostalgia ain’t what it used to be.
