Save the Children, the organization has put together a short video, directed by Kevin MacDonald, depicting the situation, which features the lyrics “I’m Gonna Be Your Friend”, to raise money and awareness for its philanthropic work.

Stars like Lady Gaga, U2, Beyonce, Muhammad Ali, Jennifer Lopez, Muse, Coldplay, Elton John, Britney Spears, Bruno Mars, Robert Plant, Kanye West, Madonna, Justin Bieber, Sting, Rihanna and more have pledged to help promote the video and charity song through their networks.
