Prince Harry’s Sentabale charity will host a special fundraising charity concert headlined by Coldplay in Kensington Palace Gardens on Tuesday evening. Besides, the Basotho Youth Choir will also perform at the charity concert. The choir consists of Mutsu, 16, who is very close to 31-year-old Harry.

The teen traveled to the U.K. with a choir of five boys and six girls, helped by Sentebale charity. On Monday, the prince met Mutsu and 11 of his friends, during their first ever overseas trip to London. The group consisting of kids and teens were busy rehearsing with Sentebale Ambassador Joss Stone at the Brit School in Croydon, South London when the Harry walked in unannounced.

The prince met Joss and then walked towards Mutsu, who was delighted to see Harry again. The Lesotho lad presented Harry with cards and gifts from his country. The memento included a small model of a traditional hut and a framed set of three photographs of him at different ages.

Mutsu and Harry met when the latter was 19 in his gap year and visited the Lesotho. The two became fast friends, stayed in touch and met in November last year when Harry visited the country to open the Mamohato Children’s Center. When Relebohile ‘Mutsu’ Potsane and Harry met in 2004, the latter was only four- year-old.

The kids from the choir are supported by Sentebale’s Secondary School Bursaries Progam or Care for Vulnerable Children Program. The group arrived in the U.K. on Thursday and have traveled only up to Pretoria, South Africa by bus for their visas. However, the choir members between the age group of six to 19 years enjoyed a river cruise on the Thames and an open-topped bus sightseeing tour over the weekend.

The trip was arranged by Avios Travel Awards, which also paid for their flights. The members have never been on a plane or boat before, nor had they tried British food. Molise, an 18-year-old said that she hoped to study medicine in London next year. Ntebaleng, 19, said that she loved the fish and chips.

The Sentebale Concert will raise funds to support the charity’s work helping vulnerable young people in Lesotho. It will also shine a light on challenges faced by charities to support young people with HIV.
