Hollywood actress Sharon Stone will join British musician Yusuf Islam and a cast of young singers on stage at a special charity event in Switzerland later this year (13).

The Basic Instinct star will serve as a narrator in the original musical, which will be staged in Geneva in honour of Green Cross International, an environmental organisation set up by former head of the Soviet Union, Mikhail Gorbachev.

Islam, formally known as Cat Stevens, will also take part in 2050: The Future We Want along with 40 young people and a 100-strong choir.

The show will take place on 3 September (13).
