Many thanks to SRAA contributor, Dan Srebnick, who shares the following recording and notes:

This is a very enjoyable review of the first 25 years of Radio Nederland, hosted by Jerry Cowan. It is the complete broadcast with the news, which at the time was feed via HF from Hilversum to Bonaire. The panel of guests include Bruce Parsons, Neville Gray, as well as the head of the English Department of Radio Nederland, Van Dulken.

It was recorded off air in Queens, NY on 11,730 kHz between 0200-0320 GMT (April 16 GMT). It came from the relay site in Bonaire, Netherlands Antilles where RNW had a powerful relay transmitter site. There is some interference but not enough to diminish your enjoyment.
