Do not, if at all possible, miss the final part of Two Episodes of Mash (Radio 2, Saturday night). This is a very funny, inventive and engaging comedy show, written and performed by Diane Morgan and Joe Wilson. It is also quiet (no studio audience) and therefore intimate, welcoming you into its various fantasy worlds where a sheepdog colludes with a sheep and a queen bee finds out what's really happening in her hive from a wasp who's joined for the fringe benefits.
