*Beyonce literally sang for the world on Friday.
The singer performed her track “I Was Here” in the General Assembly Hall of the United Nations in honor of World Humanitarian Day, which is Aug. 19, and received rave reviews from officials and stars, MTV reports. A music video of the performance will debut the same day.
“Is this what happens at the U.N. every Friday night?” Anderson Cooper, who hosted the event, asked the crowd. “Because, I’ve gotta tell you … I wanna be here every Friday night if this goes on.”
Among the hundreds in attendance were actress Julia Stiles, R&B singer The-Dream and songwriter Diane Warren, who wrote the tune.
Warren said in an interview that she initially called Beyonce’s husband, Jay-Z, and played the song for him over the phone. He quickly called Beyonce, and days later she recorded it. It appears on her album “4,” released last year.
Video of Beyonce’s performance will be released on Aug. 19 on World Humanitarian Day, which commemorates 22 humanitarian workers who were killed in a 2003 terrorist attack in Iraq. A website, WHD-IWasHere.org, was created with hopes of getting 1 billion people to pledge to help someone in need.
“I’d like to ask everyone to make sure they’re a part of August 19th,” Beyonce said from the stage. “It’s such a beautiful, beautiful day, and I’d like to honor the 22 people who lost their lives. God bless you all. Thank you so much for having me.”
