It is the second year of the open-air concert held in London's Hyde Park in aid of the Prince's Trust charity.

The Prince of Wales is also set to attend the party, which is sponsored by London radio station Capital FM.

Culture Club singer Boy George joked that the biggest thrill of playing in the park would be the chance "to pinch Prince Charles' bum!"

He also said he was delighted that Culture Club had been asked to take part.

Other acts which have have been confirmed include Madness, Martine McCutcheon, Honeyz, Roxette, Shania Twain, UB40 and Westlife. A further 10 acts are to be announced before the 4 July concert.

The eight-hour party will start at midday with Capital FM DJs, including Chris Tarrant, Steve Penk and Dr Fox, introducing the line-up.

Last year's performers included All Saints, Robbie Williams and Louise and the young Princes Harry and William also attended. The whole day raised more than £500,000 for the Prince's Trust.

Capital Radio group programme director Richard Park said: "Last year was a huge success on a glorious sunny day in front of a highly-charged and enthusiastic crowd.

"After just one year, this concert has established itself as a key part of the London event calendar."
