In an interview with Us at that time, Stump clarified that the band behind such hits as "Sugar, We're Goin Down" and "Dance, Dance" had not broken up. "We just kind of stopped touring, not with any degree of permanence. To my knowledge, the band is not broken up, but we did really need some space and a break, and there were really legitimate creative differences," he said. "None of those differences were interpersonal at all. I love those guys, I have nothing against those guys at all, and I definitely miss playing with them."
