A STAR-STUDDED concert in tribute to Queen Elizabeth's diamond jubilee was overshadowed as Prince Philip was taken to hospital with a bladder infection.
Take That singer Robbie Williams opened the show by declaring to thousands of fans: "Let me entertain you."
But Prince Philip missed the night of music and was said to be "disappointed" at not being able to attend the show featuring some of the biggest names in pop due to his illness.
Paul McCartney, who was closing the show with three songs, wished the prince well, saying: "I think, you know, we all send our best wishes for a speedy recovery. I hear he's not too bad."
Philip is being treated at the Edward VII Hospital in central London and will be kept in for observation for a few days, Buckingham Palace said.
On Sunday, he joined his family on the royal barge during the diamond jubilee pageant, standing for much of the day, and he did not look to be in discomfort.
Williams was the first act on a bill studded with big names who all answered the call to perform for the queen.
She was missing from the royal box at the beginning, though many members of her family were already watching the show.
