WORCESTER -- It hardly matters whether one thinks "American Idol," and the ready-made pop stars it produces, is a great egalitarian pop-culture phenomenon or simply the opening act for the Four Horsemen of the Apocalypse. Monday night, there was no denying the effervescence exuding from "Idol" alums Kelly Clarkson and Clay Aiken.
So what if it was all cheesier than the lunchtime menu at Papa Gino's? Both Clarkson, the winner of the show's inaugural season, and Aiken, the second season's runner-up, performed hourlong sets so filled with gratitude and energy there was no room left for airs common among many pop stars. Both seem to understand they're just a couple of lucky so-and-sos plucked from obscurity.
