Kerry Thompson mined the depths of the NPR archive for September's episode of Playback, the podcast that revisits NPR's finest from 25 years ago this month. Not only did she unearth a classic piece on chair calisthenics, she also dug up a story about a brand new technology called the CD. In addition, there's some great interviews with comedian George Carlin, Shoe creator Jeff MacNelly, and an "oh so very young" Ellen DeGeneres. This month's episode also features another installment of "First File", the occasional series where we interview NPR's best and brightest about the very first piece they ever filed. Up this month is Art Silverman, a producer for All Things Considered, with his first piece entitled "Rat Olympics". It's destined to be a classic in the annals of NPRness.
