The program may be available at the npr.org site, on RealAudio. Failing that, you can order cassettes of most NPR programs for a nominal fee. For additional fun, you can listen to Chinwag Theater, (carried by numerous public radio stations--yours may be one, or planning to be), on which you can hear me read various things...and rumor has it that you may hear another familiar radio voice or two from time to time.
P.S. ""Young Larry,"" by Daniel Pinkwater, has twins in it.
