B.B. King’s openers had a rough time. As an announcer welcomes the likes of Sheriff Joseph Woods to the stage before the blues legend takes the stage for a 1970 show at Chicago’s Cook County Jail, the prisoners greet the officer with aggressive boos and jeers. It was a tough crowd, but King entranced them with ease and humility. He was gracious, flirtatious and even self-deprecating as he effortless ripped through songs like “Worry, Worry” and “Sweet Sixteen.” “It was the best show we ever had,” said the Department of Corrections Superintendent Winston Moore who had invited King to perform for the prisoners. By the time he finished on a sweet note with the ballad “Please Accept My Love,” King had the crowd on their feet, hollering ecstatically. Brittany Spanos
