NPR's year-long Friday collaboration with independent producers Jay Allison and the Kitchen Sisters (Davia Nelson and Nikki Silva) — a series called LOST AND FOUND SOUND. Today we present an item from our QUEST FOR SOUND, in which listeners call 202-408-0300 and tell us about recordings they have - or have stumbled upon. Reverend Dwight Frizzell of Kansas City, Missouri found a recording of the late President Harry S. Truman from 1957 — five years after Truman left office. The tape is of Truman dedicating a shopping center to be built on the site of his boyhood home. With music Frizzell and a friend added, this remarkable speech winds up being a powerful, and unintended elegy to a passing era.
