Last night's zippy American Idol was a producer's dream—literally. The show's producers finally realized the dream of an all-David finale they'd been pushing for since mid-season, knocking Sayesha Mercado out of the running. Of all the contestants in season seven, it stands to reason that both David Cook, arguably the most musically original of the set, and David Archuleta, the most vocally gifted, should battle it out in what judge Simon Cowell hopes is a "humdinger" of a competition—whatever that means. It should be an evenly matched competition: the handsome young teen heartthrob versus the cute bartender-cum-accidental rock star.
