Why They Split: Years of tension within Oasis finally reached a boiling point backstage at a Paris festival in August of 2009. Reports vary wildly about what happened, but the Gallagher brothers got into some sort of physical altercation and then refused to take the stage. The rest of the tour was canceled. "With some sadness and great relief I quit Oasis tonight," Noel Gallagher said in a statement. "People will write and say what they like, but I simply could not go on working with Liam a day longer."
Last Performance: The final gig took place August 22nd, 2009 at the V Festival in Weston England. The Paris fight was six days later.
Odds Of A Reunion: When Oasis split, Liam Gallagher continued on with the rest of the band as Beady Eye. Noel formed Noel Gallagher's High Flying Birds. Both are rather successful, but not nearly on the same level as Oasis. The brothers have spent the last two and a half years attacking each other in the press, even as Liam expresses a desire to reform Oasis in 2015 to celebrate the 20th anniversary of (What's The Story) Morning Glory. We obviously aren't sure if that's going to happen, but a reunion at some point seems extremely likely. We'll say 85%.
