When radio legend and oral historian Studs Terkel wrote the book “Working” in 1974, based on interviews he did with Americans of all social strata, it was hailed as a groundbreaking achievement, since it did what no popular study had done before. It celebrated America’s workers.

The book was turned into a musical in 1978 and had a short run on Broadway, but “Working — A Musical” is not often produced. Fortunately, Keegan Theatre is bringing it back in a rousing, updated version, one that highlights what a friend of working people Terkel was.
