In the late Eighties, Guns 'n' Roses were the biggest, baddest, band on the planet, a rock 'n' roll juggernaut that played era-defining songs like "Sweet Child 'O Mine" and "Welcome to the Jungle" to packed stadiums around the globe. They were a band so utterly convinced of their own greatness that they released not one, but two double albums on a single morning. But their excess was not just a feature of their recording career. Their offstage antics were legendary. Spleen bursting quantities of drugs and booze fuelled a rapacious appetite for groupies and bad behaviour. They learnt from the debauchery of the seventies and they topped it. And in the end it all crashed down in flames. Now Steven Davis, author of the classic rock bestseller "Hammer of the Gods", his biography of Led Zeppelin is telling the whole story for the first time. Years of research and exclusive interviews make this the definitive story of the one of the greatest rock bands the world has ever seen.
