There was much more to Brendan J Byrne’s engrossing, even-handed documentary 66 Days (BBC Four) than its title might at first suggest. The timeline that led up to the death on 5 May 1981 of the IRA prisoner provided its immediate context – an increasingly dramatic one as the countdown of Sands’s hunger strike nears its inexorable conclusion.

And now the end is near… and so Inspector George Gently faces his final case. Deemed too political to be broadcast in its original slot in May – 10 days before the General Election – Gently and the New Age was postponed until 8.30pm last night.

Repetition can help clarity. It emphasises significance, and shines a light more directly onto something hidden. It can guide us gently into an area we might have otherwise circumvented, and urge us to stare at something for long enough to see beyond, and transcend previous, long-held opinions. It can also, of course, become very tired very fast and that was, sadly, the case with the third series of John Morton’s BBC mockumentary sitcom.

The streets around Grenfell Tower on the morning after it was consumed by fire heaved with people. A stream of donors brought food, clothes and toiletries, while news crews and journalists came in vans or on foot as if arriving in a war zone. Not half a mile from the smouldering sarcophagus, I cycled past a primary school with children playing as normal in the playground, and wondered if this was what the Blitz was like. An unfathomable disaster on the doorstep.

Hyperbole be damned. The most iconic English classical recording was made on 19 August 1965 in Kingsway Hall, London. Like Maria Callas singing Tosca, Jacqueline du Pré simply was the Elgar Cello Concerto once the LP hit the shops in time for Christmas. Proud, diffident, exuberant, reserved – all those words the English once used of themselves became freely associated with both performer and work, the two almost indistinguishable from one another in popular imagination.

Much is being made of the fact that Kit Harington is not only playing the Gunpowder Plot mastermind Robert Catesby, but is genuinely descended from him (and his middle name is Catesby). However, despite its factual underpinnings and screenwriter Ronan Bennett’s flowery 17th-century dialogue, Gunpowder is drama in a historical vein, rather than nailed-down fact.

Chris Packham, who devises and presents programmes about nature and animals, has described himself as "a little bit weird". This autobiographical documentary about himself explained what being on the autistic spectrum meant to him in particular in daily life and beyond.

You might expect a posthumous 90-minute documentary – and that’s before you insert the ad breaks – about one of the biggest stars in British pop music over the last 30 years to shed some light on how said artist became so huge, but also how his career slowed to a crawl and his life came to such a depressing end. Freedom gives you some of the former but absolutely none of the latter.

Now we know who sent Jonas Kaufmann the Union Jack boxer shorts for the Last Night of the Proms. Whether the sender’s identity is the bigger surprise, or the hint of ambiguity over whether the "Greatest Tenor in the World" had previously heard of one of Britain’s favourite baritones – well, you decide. And no, we don’t learn who threw the knickers at him from the arena.

The first thing to say about Lucy Worsley’s Nights at the Opera (BBC Two) is that it is laser-aimed at those who have not enjoyed many nights at the opera. Enjoyed in the sense of attended; also, probably, in the sense of enjoyed.
