In an effort to gain back younger viewers, ABC will air a special rock and roll edition of Who Wants to Be a Millionaire?, the network announced Friday at the Television Critics Association press tour in Pasadena, Calif. The show, whose ratings have dropped since the first season, plans to pit hot music stars against each other in hopes to recapture the 18-49 year-old viewing group. Rock and roll Millionaire airs Feb. 11 and 14 and will feature the Backstreet Boys's Nick Carter and Howie Dorough, KISS frontman Gene Simmons, Metallica drummer Lars Ulrich, Sisq&#243, Emily Robinson of the Dixie Chicks and Sugar Ray rocker Mark McGrath.
