London, June 04: Patriotic festivities in Britain celebrating Queen Elizabeth`s 50th year on the throne hit a high note Monday with an all-star pop concert rocking the normally sedate gardens of her Buckingham Palace residence.
A beaming Brian May, guitarist of legendary British rock band Queen, started the party with a solo rendition of the national anthem, "God Save the Queen," on top of the palace roof.
The line-up also included Latin star Ricky Martin, gothic rocker Ozzy Osbourne, former Beatle Paul McCartney, Eric Clapton, Elton John, Phil Collins and a host of other singers, comedians and celebrities.
I`ve never seen a gig like it," said comedian Ben Elton, one of the concert hosts. "Here we are with Buckingham Palace behind us in the gardens, 12,000 punters have won a ticket -- I think it`s marvelous."
The "Party at the Palace" was the culmination of a day of street parties and parades honoring the 76-year-old monarch on the third of four days of festivities which have confounded cynics` predictions they would prove a damp squib.
