I just caught the last 40 minutes of Fresh Air on my local public radio station. It included a very recent interview with JLD as well as segments from a 1992 interview with Larry David, an interview with Jason Alexander (maybe 1992, also), and a 1987 interview with Jerry. It's not available yet, but keep an eye on http://www.whyy.org/freshair/fara.html for the Real Audio version (enter today's date: 5/13/98).
Funny stuff.
