Rock ’n’ roll pioneer Bo Diddley died of heart failure at his home in Florida today. According to his Wikipedia entry, Diddley, whose birth name was Ellas Otha Bates, had in recent years settled in the small farming community of Archer, Fla., near Gainesville, where he lived close to his children, grandchildren and great-grandchildren, attended church, and prior to suffering a stroke and heart attack last year had been working on some faith-based songs.
