"The theme for this week&amp;#039;s American Idol performances has been confirmed. The remaining Top 8 contestants will sing classic tracks associated with Detroit in a Motor City-themed special airing this Wednesday (March 27).  Former Idol contestant Colton Dixon&amp;#039;s return has also been confirmed by producers. Dixon, who finished seventh on the show last year, will perform an as-yet-unannounced track on the show&amp;#039;s 450th episode this Thursday (March 28). He follows in the footsteps of season 11 winner Phillip Phillips and runner-up Jessica Sanchez, who appeared on the first two results shows of the new season. Dixon, who teased his appearance last week by saying that show bosses would &amp;quot;kill&amp;quot; him if he revealed what he intends to sing, also revealed that he is a fan of Angie Miller&amp;#039;s take on his track &amp;#039;Never Gone&amp;#039;. Miller has been one of the most popular contestants with Digital Spy users in this season&amp;#039;s reader opinion polls so far. American Idol airs on Wednesdays and Thursdays at 8/7c on Fox in the US, and on Thursdays and Fridays at 8pm on 5* in the UK. &amp;#039;American Idol&amp;#039; Top 9 perform on Beatles week - photo gallery:  "^^<http://www.w3.org/2001/XMLSchema#string>
