The insights of principals on both sides of the camera, from Sheldon Leonard and Aaron Ruben on the production end to Andy Griffith, Don Knotts and Jack Dodson on the performance side, are fascinating. The book even includes a working script (season four's "The Sermon for Today") from Griffith's personal collection, which Kelly presents as good illustration of Mayberry's (usually) unhurried pace and the show's character dynamics. He's right, but a more appropriate script to share would have been "Man in a Hurry" (often cited as the series best episode) from season three.
The book closes with summaries of all 249 TAGS episodes, including official script titles, filming sequence and airing order.
All in all, this is a valuable resource for serious TAGS devotees and anyone interested in the nuts and bolts of television production. Those wanting just another feel-good book about the folks of Mayberry had best look elsewhere.
