When the 49-city "Pop-Tarts Presents American Idol Live! Tour 2008," hits your city, David Cook, David Archuleta, Jason Castro, Michael Johns and the rest of the Top 10 will be performing mini-concerts, with just a couple of group numbers thrown into the mix. So each time an "Idol" finalist comes on the stage, it will have an entirely new look.

"I really like to dance, but I really struggle to dance in heels on a slippery stage with lights and dips," shares Brooke White. "We had a limited amount of time to learn things, so it was really interesting."

For her portion of the show, Brooke will be incorporating "Let It Be" into her set -- and she will be sitting behind the piano. "That is where I belong," she tells ET. "Nobody wants me out there flapping my arms around."

Surprisingly, David Cook tells us that his favorite performance from season seven was "Music of the Night." "Growing up with a theater background, I appreciated Andrew Lloyd Webber just like everybody else," says the rocker. "Then to be able to fall back on the singing training I have had, it was fun for me, but it is not something I am doing on the tour.

"I am doing a few things. Actually, I am going to be doing the single, 'Time of My Life.' I have been blessed to have that song do as well as it has. I am really excited about it. We pushed it up a little bit to try to make it something interesting for the people coming to see the show and we have a few surprises."

Laid back Jason Castro will be reprising fan favorite "Somewhere over the Rainbow." "That was my favorite," he tells ET. "That was the only performance I could watch and not cringe and have to shut off. Every other performance I was like, 'Eww.' That song I could actually watch all the way through and I was happy with it the whole way."

Runner-up David Archuelta tells ET he has spoken with our correspondent Donny Osmond since the competition ended. "He called while he was in London getting ready for his show there. He said he was proud of me and try to be a good example. Just to remember who to thank for all of this. He said if I needed help with anything to just give him a call."

Archie will be performing Robbie Williams' "Angel," while Chikezie reveals that his tour song is one of his favorites: "I Believe to My Soul" by Donny Hathaway. "I loved it before I even got on the show," he says.

Aussie hottie Michael Johns will be doing a Queen medley, but he says those songs weren't his favorite from the competition. "My favorite performance of the season was the Dolly Parton song. It came natural to me. There were so many things that went right. When I hit that blues/soul/rock thing in my voice that is what I get excited about."

Kristy Lee Cook's choice was an easy one. She will be reprising "God Bless the U.S.A." "My dad is a veteran, so I really was dedicating that song to him," she says of her decision to sing the song during season seven. "It is one of his favorite songs. I want to sing it on tour for all the veterans. It is the only patriotic song of the night."

Carly Smithson shared that she will be performing a song she didn't do on the show -- Evanescence's "Bring Me to Life;" while Ramiele Malubay is going to be doing the Jackson Five song, "I Want You Back.

And last, but not least, third place finalist Syesha Mercado is singing Alicia Keys' "If I Got You." "I've liked it for many years and I get to do a different arrangement to it, so it is going to be cool," she says.
