Saturday Night Fry, Series 1
by Stephen Fry (BBC Radio 4, 1988)
This radio precursor to A Bit of Fry & Laurie saw Stephen Fry and guests forge ground in the comedic art of playing against expectations. It is fast, clever (if not always funny), and suavely innovative in its manipulation of the medium.
The Navy Lark, Series Six, Volume 1
(BBC, 1963)
Though tending to hammer the same nails over and over, radio sitcom The Navy Lark (any episode) showcased all the ingredients necessary to sustain a long-running comedy. Familiarity brought the audience close, breeding contentedness. Starring Jon Pertwee and Ronnie Barker, among others.
