San Joaquin Delta College drama students in May will perform the musical “Working,” a vivid portrait of the working men and women who the world so often takes for granted. Based on Studs Terkel’s bestselling book of interviews with American workers, “Working” tells the stories of a schoolteacher, a waitress, a millworker and others. The revised and modernized musical has been nominated for six Tony Awards and features songs by award-winning composers Lin-Manuel Miranda, Stephen Schwartz and James Taylor, to name a few.
