It seemed as though singer Rihanna deeply distracted by news that her beloved grandmother Clara “Dolly” Braithwaite died of cancer because on Saturday night she disappointed fans big time at a performance at a Swedish music festival. First, she arrived onstage 45 minutes late, and according to some concertgoers she appeared intoxicated. Many fans elected to walk out of Sweden’s Peace & Love Festival shorty after she hit the stage, and those who stayed turned on her when she mistakenly dedicated her version of Bob Marley’s “Redemption Song” to Norway – NOT Sweden. She had performed in Oslo, Norway the night before.
