WASHINGTON, Dec. 10 (UPI) -- PSY performed at the 31st annual "Christmas in Washington" event, days after apologizing for singing a song in 2004 calling for the deaths of U.S. soldiers.
The Korean rapper, best known for his pop song "Gangnam Style," made headlines last week after "Dear America," an old song he sang urging violence toward members of the U.S. military and their families, hit the Web.
