Anyone expecting the Smashing Pumpkins to use their 20th anniversary tour to revisit their greatest hits is in for a surprise. That much was apparent from the tour's first show in Cleveland Saturday night, as frontman Billy Corgan strutted out with an acoustic guitar and harmonica for the first three tunes of the band's two-and-a-half-hour set. "That guy lost his virginity to '1979' [and wants to hear it], but it ain't gonna happen," Corgan said in response to one fan's request. Ouch. Wearing a fresh pair of black Nike tennis shoes and a skin-tight shirt with a spider emblazoned on it, Corgan approached the show with child-like exuberance.
