4Extra have just finished an almost complete run of this series, but they didn't broadcast Series 3, eps 11, 12 & 14. Do they not have those 3 episodes?
I noticed some episodes have had parts edited in from a lesser quality (off-air) source. Presumably they used transcription versions which are always shorter, and re-instated the missing material. I wonder if they maybe have off-airs for the missing 3 but not a corresponding transcription version, and didn't want to inflict a whole half hour of lesser sound quality on the listeners?
