Welcome back to "AI Aftermath," where we explore Idol's past. Each installment, as one more American Idol hopeful is eliminated from the competition, we take a look back at contestants past who were eliminated at the same point. We'll examine how they did on the show and what they've been up to since their eliminations. In honor of David Archuleta's elimination in the finale, we'll be looking at other second place finishers.

This week: 2nd place finishers, featuring featuring Justin Guarini (Season One), Clay Aiken (Season Two), Diana DeGarmo (Season Three), Bo Bice (Season Four), Katharine McPhee (Season Five) and Blake Lewis (Season Six).

Way back in the early days of American Idol, and by early days I mean "Season Four," there was a girl who was a little bit country and a long-haired fellow who was a little bit rock and roll. I think we all know who went on to win that season, but that southern rocker was a pretty amazing presence of his own. In fact, they were so strong together in the final, they both released "Inside Your Heaven," the Idol single for that year. And they even swapped spots at number one with the track.

Now Bo's out promoting See the Light, his latest album which is more true to his southern rock roots. But that doesn't mean he's not willing to take a break from his touring schedule to spend some quality time with the kids down at American Idol Camp this summer. The program, which began last year, is for 10-15 year olds and runs in five two-week sessions throughout the summer.

There, kids can go to learn about the music industry and hone their craft as musicians, as well as experiencing all the traditional things that make summer camps fun, just with the added bonus of hanging out with and learning from Idol alumni like Bo. For more on Idol Camp check out the official American Idol Camp website. For more on my chat with Bo Bice, follow me after the jump.

Diana DeGarmo, who is now 18 years old, rang in the New Year by entertaining American troops across the globe. The American Idol runner-up's schedule had her performing for troops in seven countries, in seven days. Tonight is her final performance, in Germany. She's also been to Qatar, Afghanistan, Bahrain, United Arab Emirates, and Iraq, where she spent the night in one of Saddam's many palaces. She's performing with comedian Reggie McFadden and country singer Michael Peterson as part of the USO Tour. Her part of the show includes pulling troops up on stage to compete in an impromptu-style dance contest and she wraps up each performance by singing America the Beautiful.
