The Kelly Clarkson and Clay Aiken concert

The Kelly Clarkson/Clay Aiken concert Monday night at the United Center was exactly what you would expect from a pair of winners — well, one winner and a runner-up — from “American Idol.” It was sweet, earnest and well rehearsed, but not particularly memorable. While it’s clear that each performer has a strong set of pipes, neither has toured enough to put on a truly exhilarating live show. You can sit home and listen to their CDs and pretty much get the same experience.

Nice guy Clay Aiken wins first place in fans’ hearts

Let’s face it. We’re not a society that recognizes No. 2 — except when it comes to Clay Aiken. The runner up in last year’s “American Idol” contest has proved to be the little Southern boy who could. His debut album, “Measure of a Man,” easily outsold first-place winner Ruben Studdard’s effort. And Aiken’s the one headlining a tour with Kelly Clarkson, the first “American Idol” winner.
