The whole of the BBC’s Comedy Connections on Ever Decreasing Circles is on YouTube, divided into four parts. It’s full of interesting titbits, asks a few unanswered questions, and contains what is probably the last filmed interview with John Esmonde. I’m only able to embed the first two parts, because of an advanced case of technothickery.
