Radio
There are a LOT of old "western radio" shows in the "public domain" - you can download them at the Internet Archive.
The problem actually becomes that there are SO MANY it is hard to keep track of programs.
There are a lot of POSSIBLE solutions to that problem -- one is to do a "internet radio station" - maybe something like this "Classical music" example
Another option is something like audiobookshelf.org
That is the plan at least ...
