MANDELA WATCH

The Heart of Rock ‘n’ Roll: Grammy winner Bonnie Raitt, who performed at the freedom rally honoring Nelson Mandela in Oakland Saturday, said Mandela told her that he credits the Wembley rock concert tribute to him two years ago with focusing attention worldwide on the anti-apartheid struggle. She said Mandela was especially pleased by the number of young people who were politicized about the issue, thanks to the concert. Raitt, who talked with Mandela at the African National Congress fund-raiser Friday night, said that’s why Mandela made a special point of thanking musicians at this year’s Wembley concert.
