Former South African president Nelson Mandela is to share a stage with Mick Jagger, U2 and a bevy of models in a charity concert to be held in Barcelona on June 30, the organisers said on Wednesday. The “Frock and Roll” event is being put on to raise money for the Nelson Mandela Foundation for Children. Other groups set to perform include Chrissie Hynde and the Pretenders, UB-40, Macy Gray and Wyclef Jean from the Fugees, while supermodels Naomi Campbell, Kate Moss, Elle MacPherson and Helena Christensen will be on hand to lend a bit of glamour. – AFP
