(CNN) - They'll appear on the show–but they won't be singing. At least, not that we know of.
The hit TV series American Idol will broadcast a special edition Wednesday night to serve as a fundraiser for six charities. And the presidential candidates will be all be on hand, even if it is only via video tape.
Democrat Barack Obama's campaign confirmed Tuesday that the White House hopeful sent in a pre-taped video message encouraging viewers to make a donation to "help make this world a more just, more equal, and more hopeful place to live."
According to the script provided by the campaign, Obama also added that his two girls, Sasha and Malia, are "big American Idol fans." He also commended American Idol and said that "when ordinary people come together they can do extraordinary things," a common line from his stump speech.
Fellow Democrat Hillary Clinton and Republican John McCain are also expected to appear at some point during the broadcast.
