When U2's lead singer and Microsoft's chairman get together, the talk turns to charitable work.
Bono's buddy Bill Gates
Their day jobs are vastly different, but Microsoft Chairman Bill Gates and U2 lead singer Bono (left, seen here in a photo from February 2002) have a shared interest in charitable work in the developing world.
At the World Economic Forum in January 2005, Gates and Bono shared the stage with political leaders prior to a session called "The G-8 and Africa: Rhetoric or action?" (From left: Former U.S. President Bill Clinton, Gates, South African President Thabo Mbeki, British Prime Minister Tony Blair, Bono and Nigerian President Olusegun Obasanjo.)
