Rock and royalty joined forces for a very important cause on Tuesday (December 6).
The Duke and Duchess of Cambridge, William and Catherine, along with Prince Charles and Camilla attended the Prince's Trust concert starring Gary Barlow.
The organisation raises money to help young people.
SOUNDBITE: Singer Gary Barlow, saying (English):
"I hope you enjoy tonight and I hope it's not too loud."
SOUNDBITE: Prince William, saying (English):
"The louder the better, the louder the better."
Like she did at her much-watched wedding this summer, Catherine seemed to be in awe at the sheer scale of the audience.
After singing the national anthem, Barlow then rocked the crowd with Take That hit "Greatest Day".
Barlow said playing before the royals was an honour for him and the charity itself was also close to his heart.
SOUNDBITE: Gary Barlow, Singer, saying (English):
"In particular a lot of the money raised tonight will go to the riots foundation that happened last summer and that's obviously important to us all, being in London, living in London, and so that's a really important thing about tonight."
Afterwards, the royals met Barlow and other performers to thank them personally for their efforts.
It's hoped the two-day shows will raise a total of 630,000 USD (400,000GBP) for the Prince's Trust.
