Ricky, Shania, Geri Turn Out For Prince's Trust

Ricky Martin, Shania Twain, Geri Halliwell, and Boyzone were among the artists turning out Sunday night in London for a pop-filled installment of the annual Prince's Trust concert.

The event (saddled with the unfortunate moniker of "Ricky Martin, Shania Twain in Concert for The Prince's Trust Party in the Park '99 with Geri Halliwell and Boyzone") was staged at London's Hyde Park this year. Those who couldn't make it to the U.K. for the show but want to catch the action anyway will be pleased to note that a pay-per-view special is being put together and will air in the States on September 23.

The Prince's Trust was established more than 20 years ago and aims to support 14 to 30-year-olds who have a hard time getting a leg up on a productive future. So far, the organization estimates that it has helped 40,000 young people start their own businesses.
