ORANGEBURG, S.C. – James Brown knew all along that he wanted to open a museum that would inspire people – especially the poor – to pursue their dreams. So he carefully saved all of his belongings, from his glittering suits and glossy shoes to the comb he used to neatly sculpt his hair. The soul singer, who died Christmas Day 2006, says as much at a new exhibit on the music icon that showcases the attention he paid to his roots, his eclectic tastes and his showman’s image.
