Stevie Wonder performed free pop-up concerts in Washington, Philadelphia and New York on Monday.
The D.C. Office of Motion Picture and Television Development says Wonder performed a few songs at the D.C. Armory Mall Monday morning. The first 1,000 people got doughnuts.
The concert is part of a news conference promoting Wonder's "Songs in the Key of Life Performance" tour.
In Philadelphia, a huge crowd gathered at Dilworth Park to hear hits including "Superstition" and "Uptight." Wonder took questions from the media and spoke against gun violence.
Wonder also performed in New York's Central Park Monday night.
Wonder's tour will stop in Washington on Oct. 3, in Philadelphia on Oct. 7 and in New York on Nov. 24.
