POP idol Michael Jackson said on Tuesday he will stage two concerts in June to raise funds for South African President Nelson Mandela’s children’s fund, the Red Cross and UNESCO. The first concert will be held in the Olympic stadium in Seoul on June 25, and will be followed two days later by a performance in the Olympic stadium in Munich, Germany. Jackson refused to answer questions, but one of his aides said performers will include tenor Luciano Pavarotti, soul star Stevie Wonder, Italian heart throb Eros Ramazotti, German band the Skorpions and R&B group Boyz II Men.
