Puff Daddy [ tickets ], Sting [ tickets ] and Bryan Adams [ tickets ] are among the new acts confirmed to play a set at one of three Net Aid benefit concerts to take place on Oct. 9 in three countries. New details about the shows -- which aim to promote worldwide poverty awareness -- were outlined by Quincy Jones, Bono, David Bowie, Sean "Puffy" Combs, Wyclef Jean, and UN Secretary Kofi Annan during the official launch of the new Net Aid web site (www.netaid.org) on Wednesday (9/8).

For the web site's launch, U.S. President Bill Clinton, former South African President Nelson Mandela and British Prime Minister Tony Blair were linked from their offices via a live Internet broadcast to cut the web site's ''virtual ribbon.'' Organizers want to log one billion hits on the site during the concerts, which they hope will lead to millions of donations of time, expertise, goods or money.

Confirmed to play sets during the Giants Stadium show near New York are Mary J. Blige, Bon Jovi, Busta Rhymes, Counting Crows, Wyclef Jean with Bono, Jimmy Page & friends, Puff Daddy, Sting with Cheb Mami, and Zucchero. Tickets for the East Rutherford, N.J., show go on sale Friday (9/11) at 9 a.m. EDT.

Taking the Wembley Stadium stage in London will be Bryan Adams, David Bowie, Bush, Catatonia, The Corrs, The Eurythmics, George Michael, Stereophonics, and Robbie Williams. Tickets for the British show are currently on sale. The invitation-only show at the Palais des Nations in Geneva will feature Des'ree, Bryan Ferry, Michael Kamen & Orchestra, and Texas.

Sheryl Crow and Jewel [ tickets ] have also confirmed, but not for a specific venue.

During their performance, Bono and Wyclef will perform ''New Day,'' a song they recorded for Net Aid and the Wyclef Jean Foundation, a non-profit organization which donates musical therapy, instruments and lessons to underprivileged children throughout the world. The single, to be released by Columbia Records, will be in stores Sept. 14.

During the Net Aid press conference, Bono said he supports Net Aid because the organization supports the cancellation of Third World Debt, which he considers the first step toward eliminating extreme poverty.

Money raised through the Net Aid web site will go to anti-poverty projects worldwide. Net proceeds from the concerts will help specific populations in extreme poverty in Kosovo and African countries. The web site will be turned over to the United Nations Development Programme after the concerts.

VH1 and MTV will broadcast the concerts in the US, and BBC television and radio will carry them in the Great Britain. Radio Express will distribute a radio feed of the concerts worldwide, and NBD Television Limited has lined up television networks in 17 other countries to broadcast the show. The entire event will be webcast live on two channels -- one carrying the concert, the second showing backstage scene -- via the Net Aid site.

Organizers describe Net Aid as an attempt to inspire action by bringing together for the first time the power of the Internet, television, radio, and world-renowned artists and producers. Among the producers responsible for the event are David Goldberg, Harvey Goldsmith, Ken Kragen, Don Mischer and Jeff Pollack. The producers had a hand in previous global awareness efforts including Live Aid, We Are the World, and Hands Across America.
