To enter, visit the musical's Facebook fan page and click on the "Cell Block Idol Contest" tab. Submit your name, email and a YouTube video of yourself singing one of your favorite Chicago tunes by Oct. 7. The video will be posted to the Facebook page for Chicago fans to "like" and assist DioGuardi in the judging process. The leading lady will make a decision by Oct. 14, and the winner will receive dinner at B. Smith's, tickets to the show and special meet-and-greet.
DioGuardi is playing an eight-week limited engagement through Oct. 30 in the Tony Award-winning revival of Chicago at the Ambassador Theatre.
