(Reuters) - A funeral for the late soul music star Aretha Franklin has been scheduled for Aug. 31 in Detroit, following a two-day public viewing of her casket, and her body will be entombed at a family gravesite, relatives announced on Friday through a publicist. Franklin, the preacher?s daughter whose powerful voice made her the long-reigning ?Queen of Soul? with such hit songs as ?Respect? and ?Chain of Fools,? died on Thursday at the age of 76.
