WASHINGTON -- Stevie Wonder is performing free pop-up concerts in Washington, Philadelphia and New York.

The D.C. Office of Motion Picture and Television Development says Wonder performed a few songs at the D.C. Armory Mall on Monday. 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.

Live Nation Vice-President of Booking Ted Mankin tells WTOP-FM that Wonder will perform in New York on Monday, too.

Wonder's tour will stop in Washington on Oct. 3, in Philadelphia on Oct. 7 and in New York on Nov. 24.
