American Idol's Top 11 finalists return for a special live episode to allow for voting to take place again. (A graphics glitch in Tuesday's show may have caused confusion in the voting process.) The 11 contestants' performances will be repeated during this LIVE hour. Voting will take place for two hours following the end of the telecast in each time zone. Only these voting results, not Tuesday's, will determine who will survive another week in the competition and who will go home. Tune in to see who impresses the judges and who buckles under the pressure on Wednesday, March 23 Tonight's theme: Billboard top 100 hits. Performing tonight: Anthony Fedorov, Anwar Robinson, Constantine Maroulis, Harold "Bo" Bice, Nikko Smith, Scott Savol, Carrie Underwood, Jessica Sierra, Mikalah Gordon, Nadia Turner, and Vonzell Solomon.
