The Wiggles are the unlikeliest of global superstars. With their bold coloured skivvies and a core fan base under five years old this is arguably the most distinctive music group in the world. Over the decades, the childhoods of generations of pre-schoolers and their parents have been infused with the primary emotions of joy, optimism and an unstinting idealism. It’s a kind of happiness that’s hard to quantify but whose effect pays dividends for anyone touched by it. What is this bottled brightness? This is the story of The Wiggles.
