Dates have been put in front of filenames so that they are listed in chronological order. Dates are in YYYYMMDD format. Some of these dates may be a little bit out, especially when the DD at the end has been left as 00. So let us know which dates and file-names are wrong if you'd like to help.
Anyway, You will find :
Playlist of Shows: pick and play MP3s —
Get This 2006 and Get This 2007
(both are playlists in the dropdown).
Podcast feed of the full shows: in Apple Podcasts / Overcast / Pocket Casts, use "Add by URL"
→ https://purehumbug.com/feed.xml. It won't appear in Apple's directory search.
Other podcast apps, probably similar.
