The royal abode opened up its East Lawn to a charity concert to raise money for Prince Harry's Sentebale charity and to raise awareness of youth affected by HIV/Aids in sub-Saharan Africa.
"What we know is that HIV is a virus that thrives off silence and feeds on stigma," said Prince Harry before introducing Coldplay to the stage. "Every single one of us has a responsibility to educate ourselves. To do what we can to speak out and stamp out the silence, ignorance, and fear that the virus needs to win."
