Prince Harry joins Coldplay for duet at HIV charity concert

The Prince also assured the band that Queen Victoria, 'would have been a massive Coldplay fan'

Looks like Coldplay have a new member; temporarily, at least.

Hot off their headline slot at Glastonbury 2016, the band was joined by Prince Harry to sing their track "Up&Up" at a special charity concert held at Kensington Palace, organised by the Prince's charity Sentebale in an effort to raise money to fight HIV/Aids (via The Telegraph). The spectacular finale also saw the stage graced with Sentebale co-founder Prince Seeiso of Lesotho; alongside a 12-strong choir from the kingdom.

The Prince had earlier introduced Coldplay to the stage; jokingly apologising for the fact a statue of Queen Victoria on the Palace's lawn had her back turned to the stage. He remarked that she was, "surely the only person who has ever had their back to Coldplay"; while adding, "I'm sure she would have been a massive Coldplay fan".

The concert follows an earlier announcement that the Prince will be intensifying his efforts with the charitable organisation through a new series of engagement and meetings; in July, he will travel as Sentebale Patron to Durban in South Africa for the 2016 International Aids Conference, in order to meet experts in the field and deliver a speech to delegates.

Though progress has been made in reducing the number of new HIV infections globally; a lack of education and cultural stigma still leads HIV to be the number one cause of death in individuals aged 10-19.

"Lesotho faces profound challenges – and its children, one in three of whom are orphaned, suffer deeply as a result," Prince Seeiso stated. "Since my own childhood, our small nation has been ravaged by the HIV/Aids pandemic. Now 21,000 young people between the ages of 10 and 19 are living with HIV. Only 30 percent of those have access to any treatment."

Sentebale offers psychological supports to adolescents living with HIV in Lesotho, alongside providing care and education to orphans, children living with disabilities, and young shepherds known as "herd boys".

"The world has committed to ending the AIDS epidemic by 2030, but ignorance and misunderstanding continues to undermine those efforts," stated chief executive of Sentebale, Cathy Ferrier. "Together we have an opportunity to end an epidemic that has defined public health for a generation but it won’t go away unless we act now."

The concert was the very first to be held on Kensington Palace's famous East Lawn.
