I found an old .bkf from several years ago. Extracted the music folder, and found
>attached
which is a pretty okay recording, and 1:55. The YT vid at atojICwIZeg on the other hoof, is 4:12, and sounds like it was recorded from the hallway, through a closed though hollow-core door.

Because I haven't thought of this in a very long time, I'm betting you haven't either.
You're welcome?
I'm going to round this post out with some other old music that you may not have encountered too much, depending...
