Watch: Prince of Wales teases Charlotte and George during concert

Prince George and Princess Charlotte may have been impressed when their father appeared on stage to deliver a heartfelt speech in tribute to his own “pa”.

But they were noticeably less so when he attempted to amuse them by waving his Union flag in their faces.

The Prince of Wales was spotted larking around with his two elder children as they enjoyed the Coronation Concert in Windsor.

With prime, front row seats in the Royal Box, the family appeared to be having a whale of a time, dancing and singing along to Lionel Richie, Katy Perry and Take That.

While Prince George, nine, belted out the chorus to Richie’s hit All Night Long as he waved his Union Jack.

Princess Charlotte, eight, also burst into song as she sang along to Perry’s Roar next to the Princess of Wales, who waved her flag.

Charlotte, who celebrated her birthday last week, could also be seen singing along to Steve Winwood’s Higher Love.

But it was considered a step too far for Prince Louis, five, who arguably stole the show on Saturday with his animated display and who was almost certainly in need of an early night.

Speaking before the Coronation, Kate told how the couple’s three children were all a “bit nervous” and “excited” for the King’s ceremony.
