Stevie Wonder Performs for Dozens, Then Thousands, at Ohio Obama Rallies

Stevie Wonder warms up the crowd during a campaign rally for President Barack Obama at Fifth Third Arena November 4, 2012 in Cincinnati, Ohio.

Less than 200 people were on hand Saturday morning to watch Stevie Wonder at a surprise get-out-the-vote rally for President Barack Obama at Cleveland State University.

The early voting event, which is designed to draw in people who are then sent on buses to a polling place, was not announced until about an hour before the music icon took the stage.

"I do a song. You go vote. You come back. We do some more music," Wonder said, according to The Plain Dealer.

The singer did his part, playing "Sir Duke" for the smattering of fans, who proceeded to stay put. Wonder continued with his set, eventually finishing with "Superstition," but no prospective voters boarded the buses at any time.

"Perhaps it wasn't advertised properly, but the people who are here are fired up," said Bill Milhoan, of Mentor OH, who said he had not voted yet.

Obama for America Ohio, which hosted the rally, told its 34,000 followers about the Wonder appearance 30 minutes before the singer took the stage at 1:30 a.m.

The Washington Post pegged the amount of fans in attendance in Cleveland at about 50 people.

On Sunday, Wonder played for an estimated 15,000 people gathered in Cincinnati, delighting supporters with an altered version of "Signed, Sealed and Delivered" with the Obama slogan, "Fired Up! Ready to Go!" Watch:
