It's unclear exactly happened backstage at the Rock en Seine festival in Paris in August 2009, but nobody disputes that Noel and Liam Gallagher had such a horrific fight that they refused to take the stage. Some reports suggested that Liam smashed one of Noel's guitars in the midst of a vicious brawl, but neither side has ever confirmed that. Fans wrote it off as yet another fight — until Noel posted a note on the band's web site later in the week. "I have been forced to leave the Manchester rock 'n' roll pop group Oasis," he wrote. "I feel you have the right to know that the level of verbal and violent intimidation towards me, my family, friends and comrades has become intolerable." Over a year later there's no sign they plan on patching things up. "Liam has said that the idea makes him vomit and it would never happen, so I don't need to add anything to that," Noel told Rolling Stone in August. "I don't need the fucking money, but I think it's a shame that songs like 'Champagne Supernova,' 'Rock and Roll Star,' 'The Importance of Being Idle' and 'The Shock of the Lightning' will never be played again. In a stadium."
