This is a recording from a radio program given as social media sharing due to the special interest of the recording. This recording is shared non-commercially, and is not currently or foreseeably available other than by means such as this. On publishing this here, I can't find the audio documentary available commercially. The special interest, non-commercial social media sharing and that this recording is not available in any other way indicate fair use exceptions to copyright. That is so for this shared publication, and the radio station maintain the recording copyright, this is not a public domain recording. This recording is made with basic home equipment and isn't intended to be representative of the broadcast programme quality-wise.
Originally broadcast on B.B.C. Radio 2, United Kingdom, last on 4 July 2009.
