Prince Harry and Coldplay came together on Tuesday night to rock out for a good cause. The band headlined the first-ever concert in Harry's backyard (aka the East Lawn of London's Kensington Palace) to raise awareness and money for his charity Sentebale.

The prince founded Sentebale—which supports young people affected by HIV/AIDS in sub-Saharan Africa and means "forget me not" in Sesotho—in 2006 with Lesotho's Prince Seeiso after a gap year visit to the African country.

Before introducing Coldplay frontman Chris Martin, Prince Harry delivered a moving message to the crowd of 3,000 people. "What we know is that HIV is a virus that thrives off silence and feeds on stigma," he said. "Every single one of us has a responsibility to educate ourselves. To do what we can to speak out and stamp out the silence and fear. We must follow the example of Lesotho and meet one of the great challenges of our generation with optimism, energy and openness."

"That's what tonight is about. When people come together for a purpose we can achieve extraordinary things," he continued.

The fitting finale saw Prince Harry, Prince Seeiso, and a 12-strong choir from Lesotho, accompany Coldplay for their uplifting hit "Up & Up."
