The Season 2 Idol champ and runner-up's two-hour stage show, titled Ruben & Clay’s First Annual Christmas Carol Family Fun Pageant Spectacular Reunion Show, showcases their personalities and singing abilities. "Mr. Aiken has an impish mien and, we’ll later discover in an audience-participation segment, a quick wit," says Elisabeth Vincentelli. "Mr. Studdard is laid back to the point of impassivity, and his no-presence presence makes his singing all the more stunning: He has the precision and warmth of a top-shelf R&B crooner while looking as if his mind was elsewhere entirely. On Donny Hathaway’s 'This Christmas,' Mr. Studdard surfs over the notes like a sleigh effortlessly gliding over fresh snow. He is that good" ALSO: Aiken and Studdard have "fixed" "Baby, It's Cold Outside" for their stage show.
