MARRAKESH, Morocco, June 27 (UPI) -- U.S. pop singer Stevie Wonder will perform a concert in Marrakesh, Morocco, Friday to thank negotiators at a United Nations-backed forum for helping the blind.
Wonder, who is blind and is also a U.N. messenger of peace, last week appealed to more than 600 forum negotiators from 186 countries to finalize a landmark copyright treaty to enhance access to books for millions of people who are blind or visually impaired.
