Daniel replies:
It's highly complimentary of course, that you remember a commentary from 20 years ago--but it also is an example of the phenomenal retention people have of things heard on radio. It's fairly common for someone to say, ""I heard this piece you did last week""--though I stopped bothering to send things in to that particular program three or four years back--and then quote verbatim something that was aired years ago.
I'm pretty sure the piece you mention can be found in Hoboken Fish and Chicago Whistle, available from xlibris.com or amazon.com.
