Noel and Liam Gallagher, brothers who formed the core of band Oasis, have taken their sibling rivalry to new heights. Apparently last month Noel claimed that Oasis had to back out of performing at the 2009 V Festival because Liam was too hungover to go on stage. In response, Liam has filed a writ in English court, suing Noel and claiming that the true reason he could not perform was due to laryngitis. The Gallagher brothers have always seemed to be feuding, but this marks a new high. While the suit might seem silly at first blush, comments about someone’s ability to perform in their profession are given greater defamatory weight in many common law jurisdictions. Noel had left Oasis in 2009, citing only personal disagreements with Liam at the time.
