This BFI boxset of Derek Jarman films from the first phase of his career, brilliantly curated by William Fowler, is an exemplary package: a treasure trove of extras accompanies his first six features, here presented in re-mastered form, and a thorough, well-illustrated and thought-provoking 80-page booklet with extensive material about the films and a wealth of essays.

In 2017 the documentary series The Vietnam War told the story, from soup to nuts, of America’s misadventure in south-east Asia. It now seems the comprehensive history may have missed some nuts out. Not that anyone would question the sanity of a deserter from the US Army in 1968. Seen on the ground and from the air, the hot front of the Cold War was no place to be.

The similarity is intentional. The cover design of When the Day is Done – The Orchestrations of Robert Kirby nods explicitly to that of Nick Drake’s debut album Five Leaves Left. That wasn’t just the first record by the singer-songwriter, it was also first time most people heard Kirby’s string arrangements. He and Drake had been friends at Cambridge University. The album’s producer Joe Boyd commissioned arrangements by Richard Hewson but Drake rejected them and the call was made to Kirby, who had already worked with him live.

The practice of mining the rich seam of popular movies to turn them into stage plays or musicals seemingly never grows tired in theatreland. And sometimes it produces a gem but all too often it’s just a cynical ploy to attract ticket sales by piggy-backing on fond memories of a beloved film. It’s unfair to accuse this stage adaptation of Hal Ashby’s cult movie, Harold and Maude, of cynicism; the efforts of all involved are patently sincere, but sadly it just doesn’t work.

Made for Italian state television in 1978, Fellini’s Orchestral Rehearsal is full of clichés. Some of them do ring true: brass players and percussionists are often a mischievous, rowdy bunch. As for the others… I’d best stop there, lest I annoy any string-playing readers. There’s also a corrupt union official and an autocratic conductor who won’t stop talking.

What is music? When pondering archive releases, compilations and reissues the question doesn’t come up. Knowledge of context and history means there’s never a need to muse on this fundamental issue. A package, say, dedicated to Northern Soul says what it is and the prime considerations are how well it has been executed and defining its place in the relevant narrative. The same applies to anything previously covered in this column.

In 1976, when his first solo album Slippin’ Away was released, Chris Hillman could look back on being a founder member of The Byrds and The Flying Burrito Brothers, two of America’s most important bands. He had also played alongside former members of Buffalo Springfield in Manassas and The Souther-Hillman-Furay Band.

Adapted by Raymond Briggs from his best-selling graphic novel, When the Wind Blows was released in 1986 and stands up so well that you’re inclined to forgive its flaws: namely David Bowie’s leaden theme song and an abundance of fairly flat black humour. Though, in hindsight, Jimmy T Murakami’s deadpan, quasi-realist look at nuclear Armageddon as it befalls an elderly working class British couple shouldn’t be amusing.
