Prince William and son Prince George were spotted singing along to Sweet Caroline at yesterday's Platinum Party in the Palace concert.
The future kings watched the gig from the royal box, and whilst Prince George didn't seem to enamoured during the Jubilee event, he did enjoy a sing-a-long when Sir Rod Stewart performed the football anthem.
Fans were thrilled to see William and George joining in the chorus of the iconic track - however, a silent Prince Charles didn't seem to know the lyrics.
