One of the most enjoyable qualities of this consistently rewarding series is the casual way it dispenses its flow of anecdotes. Indeed, so chatty are tonight's titbits that the story of newsroom satire Drop The Dead Donkey feels more like a coffee morning than a serious look at one of the best comedies of the 1990s.

Writers Andy Hamilton and Guy Jenkin - and cast members including Stephen Tompkinson and Neil Pearson - reminisce, and a volley of clips suggests it was far sharper than many gave it credit for. As always, the revelations are a treat. Did you know, for example, that one of the original titles posited for the show was Dead Belgians Don't Count?
