Kate and William
William and Kate will complete their first joint engagement with the Prince of Wales and the Duchess of Cornwall when they attend a charity concert next month.

The Duke and Duchess of Cambridge will complete their first joint engagement with the Prince of Wales and the Duchess of Cornwall when they attend a charity concert by Gary Barlow next month.

The royal are due to attend the event on Dec. 6 at the Royal Albert Hall in London and will raise funds to help young people affected by the riots in August.

Money raised will help young people to rebuild their communities in five of the worst-hit riot areas including Manchester, Birmingham and the London boroughs of Hackney, Tottenham and Croydon.

The Take That singer will perform at two charity concerts, on Dec. 5 and 6, and part of the proceeds will go to The Prince's Trust and the Foundation of Prince William and Prince Harry, of which Kate has become a patron.

The four members from the royal family will attend on the concert's second night.

They will meet Barlow and other performers, including The Pierces, before and after the concert and during the interval they will meet some of the young people who have already benefited from the charities' work, according to a report in the Daily Telegraph.

Barlow, also a judge on reality show X Factor, said the Prince's Trust and The Foundation of Prince William and Prince Harry are "both doing great work with young people."

"It's really important to me that disadvantaged young people get the support they need, especially at the moment."
