In the early 1970's, author and radio host Studs Terkel went around the country with a reel-to-reel tape recorder interviewing people for his book Working.
The book became a bestseller and even inspired a Broadway musical - highly unlikely for an oral history collection celebrating ordinary people and their daily lives.
But until now, few of these interviews have ever been heard. Tune to KALW on Labor Day at 7pm to hear The Working Tapes, from Radio Diaries.
