Music legends pay tribute to the Queen

Elton John sang "I'm Still Standing," Stevie Wonder crooned "Isn't She Lovely," and Paul McCartney sent "All My Loving" as musical royalty celebrated Queen Elizabeth II's 60-year reign with a concert outside Buckingham Palace on Monday. But the joy was tempered by news that the queen's husband, Prince Philip, had been hospitalized with a bladder infection, The Associated Press reports.

Palace officials said the prince, who turns 91 Saturday, was taken to the King Edward VII Hospital in London from Windsor Castle on Monday as a precaution and will remain under observation for a few days.

As the Diamond Jubilee show ended, Prince Charles took the stage and encouraged concertgoers to make some noise for his father. The crowd responded with a roar and chants of "Philip." The heir to the throne paid tribute to his mother, addressing her as "Your Majesty -- Mummy" and leading the crowd in three cheers for the monarch.

Despite Philip's illness, many members of the royal family, including Charles, his wife Camilla, Duchess of Cornwall, and PrincesWilliam and Harry sat in a royal box to watch the show, performed on a specially erected stage outside the palace.

The queen was cheered as she arrived partway through the show, wearing a gold lamé cocktail dress under a dark cape. It was decided before Philip's illness that she would watch only part of the concert. She is not a noted pop music fan, and she appeared to be wearing yellow ear plugs at the show.

The lineup featured a full hand of knights -- McCartney, John, Cliff Richard and Tom Jones, all "Sirs" -- along with Dame Shirley Bassey and younger artists including Jessie J, will.i.am and Kylie Minogue.

Meanwhile Monday, McCartney confirmed he'll be the closing act at the opening ceremony of the London Olympics in July.
