A little less than a month after a string of tragic attacks shook the city of ParisMadonna made a surprise appearance at a memorial at Place De La Republique last night and played several songs for the crowd. Billboard reports that Madonna stopped by the "makeshift memorial" following a "Rebel Heart" tour performance and announced the appearance on Twitter. "We just want to sing a few songs about peace, just to spread love and joy, and to pay our honor and respect to the people who died almost four weeks ago," Madonna said. "And to spread light—we all need it."
