This is a fascinating read:
The scrap rumbles on. Electro-pop legends New Order have, intermittently, been at loggerheads for years, with bassist Peter Hook having quit the band in 2007. This week he sued vocalist Bernard Sumner and the rest of New Order for continuing without him, though the seeds for the whole debacle were sown as far back as 1991.
Every slight has been calculated and remembered to the point where no one can agree upon what really did in the band. I think it was really just money--they had more than they knew what to do with and got bored. New Order was one of the few bands from their era who made a shitload of cash (and then lost it when the Hacienda went belly up. This is largely because their records actually sold. Now that no one buys records, what's a band to do except fight over the scraps.
