Parsley Sidings: Parsley Sidings is a BBC Radio sitcom created by Jim Eldridge.  It stars Arthur Lowe and Ian Lavender (who also starred in the television wartime sitcom "Dad's Army" at that time), together with Kenneth Connor from the "Carry On" films.

Patterson (radio series): Patterson is a BBC radio sitcom about a hapless university lecturer.  It was billed as a comedy series in eight parts, written by Malcolm Bradbury and Christopher Bigsby but strictly speaking, it is a serial.  The show was produced by Geoffrey Perkins.

This is the catalyst for a catalogue of unfortunate events which sees his life rapidly crumble around him, bit by bit.  The series occupies a unique position in the history of BBC Radio 3 as it remains the only sitcom ever to be broadcast on that station.

She featured in the television adaptation of Barry Hines' "The Price of Coal", a "Play for Today" first broadcast in 1977, and as Jimmy Kemp's mother in the Hines' scripted nuclear war drama "Threads" (1984).

The names of two central characters, Ed Reardon (played by Christopher Douglas) and Jaz Milvane (played by Philip Jackson), are references to the characters Edwin Reardon and Jasper Milvain, who appear in George Gissing's 1891 novel "New Grub Street", which is set in the hack-literary London of the late 19th century, although Edward was revealed to be his given name in the second episode of the third series and Milvain is referred to as Jaz Milvane.
