Their old-fashioned brand of American swagger first found popularity in Britain, which remains for Grohl “the one place in the world I can’t walk down the street without getting recognised”. Perhaps surprisingly, American audiences were slower to warm to the Foo Fighters, although in the past decade they have picked up 10 Grammy awards, and their eight albums have sold 12 million copies. “I think that people everywhere still love the idea of rock ’n’ roll,” said Grohl. “There’s some romantic idea it represents, an old pair of jeans and whiskey and smashing windows on the way home from the bar and listening to AC/DC on 11 as you pass out in your basement. But, for years, the climate wasn’t right in America. It’s finally happening now. Now that we’re too tired to f------ do it!”
