Unless you checked out one of this summer's "American Idol" tour stops, your chances of seeing finalists Kris Allen, Adam Lambert and Allison Iraheta performing on the same stage together anytime soon are pretty slim.

But thanks to "Idol" host and Prince of All Media Ryan Seacrest, your dreams could come true one more time. Seacrest launched the "Ryan, Rock My Town" contest on Tuesday, promising fans the chance to vote for a show in their hometown by the season-eight trio. Using the Demand It! widget -- which greasepaint rockers Kiss used earlier this year to route their current tour -- Seacrest is promising the city with the most votes a free concert.

At press time, the list was topped by the usual suspects, with New York, Los Angeles and Chicago leading vote-getters, and Little Rock, Arkansas -- not far from Allen's hometown of Conway, Arkansas -- pulling up at the #4 spot. The rest of top 10 is also dominated by major cities: Boston, Dallas, Philadelphia, San Francisco, Houston and Atlanta.

The contest is slated to run through December 18. Only one vote is allowed per person, and a random drawing of entries will determine who wins a pair of tickets to the show. While the promotional image for the sweepstakes features an image of all three, the contest rules only name Allen and Lambert as performers for the concert.

The show is slated to take place on February 13, 2010.
