Found this in an article about the Euro tour announcement:
"This is a great announcement for people in Europe looking to jam with the crooning, riff-happy rockers. It’s not so wonderful, however, for fans that were looking forward to seeing them perform at this summer’s Bonnaroo festival in Manchester, Tenn., as previously reported. In short, that idea has been scrapped in favor of a European vacation.
Also, if you’re a fellow North American waiting anxiously for the band to come to your neck of the woods, don’t hold your breath. "Historically, there have been five years or so between our visits to Europe, so it's a treat to go back again so soon," says band manager Kelly Curtis, after stating that the band has no other tours scheduled for 2007."
