I just came across an excellent retrospective of Kenneth Horne's two sketch comedy series, "Beyond Our Ken" and "Round the Horne." It's a three-hour program called "Horne of Plenty" and you'll find it on BBC 7's Saturday "listen again" page through this Friday. The program includes the very first and very last episodes of both programs in their entirety, plus details of the history of the shows.

If you ever want to grab a RealAudio program for later listening, there's an excellent utility program called Streambox VCR Suite 2, which you can find various places on the web.
