Well I'm a bit diehard on Radio4 too(although sometimes listen to XFM if I'm pretending to be young and have a yearning for a radio station with music
). But this programme really was cracking.
Only thing I can't stand on R4 (apart from awful plays with people like Martin Jarvis...sorry, but there is a certain genre of ghastly comedy/play they often have on in the mornings with very posh people wittering on) is when they have a major new series and they have that woman with the really sennnnnnsuous voice speaking reaaaallly slooooowly. Makes me want to gnash my teeth and throw the radio at the wall.
