Ken's Last Ever Radio Extravaganza (playlist):
This long show had two distinct sections: The first involved many sources talking to each other, most of which were foreign-language instructional records (mostly in English). Lots of cross-cutting spoken word. Very successful.
The second was an open-access block, with various callers on the air, mostly yelling at each other, and one singing and trying to woo The Copycat (while the other callers laughed at him).
There was a lot going on during this show.
