Radio shows? Hmm… more of a wireless chap meself, Brydo. As such, recommend The Navy Lark, Round the Horne; Radio Active; Hancock; I’m Sorry I Haven’t a Clue; I’m Sorry I’ll Read That Again – indeed, anything with Tim Brook-Taylor and/or Betty Marsden. None broadcast into the ether at the moment but recordings can be found although probably on these new modern audio tape cassette thingeys!
