Recorded from a live FM broadcast by the late and much missed MM, who made a copy of his now-lost master cassette not long afterwards, using a TDK SA90 cassette and Dolby B. Flac files were created from that cassette copy in 2021 using a Sony TC-WR635S cassette deck (refurbished 2021) and Goldwave.

Two brief interruptions in the NPR broadcast appeared to have taken place during 01 and 03 as the signal briefly toggled between mono and stereo before settling into stereo. These interruptions were minimized using Goldwave.
