22 shows, about an hour each. So far I have listened to Dracula and A Tale of Two Cities. Both very good.
It’s been years since I listened to it, but I remember thinking they did a pretty good adaptation of the Man Who Was Thursday.
Of course, the most (in)famous show they did was The War of the Worlds.
The same source also provides The Lives of Harry Lime (1951-52) radio show with Welles:
“Orson Welles reprised his role of Harry Lime from the celebrated 1949 film adaptation of Graham Greene’s novel The Third Man. The radio series is a “prequel” to the film, and depicts the many misadventures of con-artist Lime in a somewhat lighter tone than the character’s villainy in the film.”
