Oasis’ Noel Gallagher announced he has left the band in a short statement posted on their website Friday night. The 42-year-old’s deteriorating relationship with brother Liam for his decision.

“It’s with some sadness and great relief to tell you that I quit Oasis tonight. People will write and say what they like, but I simply could not go on working with Liam a day longer,” Noel wrote. “Apologies to all the people who bought tickets for the shows in Paris, Konstanz and Milan.”

The group canceled last weekend’s performance at Britain’s V Festival in Chelmsford claiming Liam had contracted laryngitis. They were due to play Paris’ Rock en Seine festival this weekend. According to reports, the brothers had a fist fight shortly before they were to take to the stage.

“It all kicked off after a few jibes were thrown back and forward between them. It got totally out of hand very quickly and all the pent-up anger just exploded,” a source claimed. “Noel has been so mild-mannered and above it all, but everyone has a breaking point. The fight was split up quickly but Liam smashed up one of Noel’s guitars to make his point. That was it. The last act of anger that Noel could put up with. He just doesn’t need the hassle any more.”

The brothers have a famously fiery relationship; the ‘Wonderwall’ songwriter has quit the band before. In 2000, the two got into a drunken fight in Barcelona after Liam questioned the legitimacy of his brother’s daughter Anais. (That provoked Noel to headbutt him.) The guitarist quit the tour, leaving the remaining members to carry on without him. He later returned for their UK dates.

During their phenomenal career Oasis scored eight UK number one singles and sold over 50 million albums worldwide. Liam, 36, has apparently said the group will continue without Noel.
