Kaiser Chiefs have reignited their feud with Oasis because, well, The Sun asked them about it and they responded. As you'll no doubt remember, Noel Gallagher started it all by comparing the Kaisers, negatively, to The Monkees. This got Oasis lots of coverage for their new album, because Kaiser Chiefs, were then asked about it in every interview they did to promote their own new album. Liam Gallagher later followed up by calling them a "bad Blur", which is probably fair.
Anyway, Kaiser Chief Andrew White told The Sun: "We have no time for . Music is an art but he doesn't appreciate music for what it is. He started it. It shows what a bitter old man he has become".
