.NOTES
   Like all the functions in this module, this function expects a specific folder strucure and coding structure for each show.
   JGB and GD shows are stored in different locations and have a slightly different format:

   Dead shows are formatted:
   gdyy-mm-dd.<tokens indicating sbd/aud,etree id, <codec> znc possily BROKEN
   gd71-01-21.131517.aud.miller.flac16     # an audience recording mastered by Charlie Miller
   gd72-03-18.sbd.shnf.BROKEN              # a show whose MD5's do not check out.

Jerry shows are under the base but organised by year so:
   \jg_1975_project\jg75-05-21.lom.138271.sbd.buffalo.flac16
