Genius doesn't always tally with equal opportunities, to paraphrase Doris Lessing. Opera houses have a duty to put on new works by women composers; sometimes an instant classic emerges. But to revive a music drama that hardly made waves back in 1977? Thea Musgrave’s Mary, Queen of Scots has some strong invention, and whizzes you through historical bullet points so quickly that there’s no chance to get bored. But does it deserve a company giving it their all?

Sharks were formed in 1972 by bassist Andy Fraser after he left Free. There were two albums, line-up changes and ripples which resonated after the band spilt in 1974. A 2017 reunion album featured former Sex Pistol Paul Cook on drums. “Sophistication,” from Sharks' 1974 second album Jab It In Yore Eye, had an insistent riff Mick Jones repurposed for The Clash's “Should I Stay or Should I go.”

On its own, the second session The Lurkers recorded for the BBC’s John Peel show on 18 April 1978 is arguably a curio, a footnote. Four tracks of bracingly straight-ahead Brit-punk with a headstrong freshness undiminished by time. But whatever the impact, The Lurkers were never a main-agenda band, and the Peel session was an adjunct to their discography.

“A band you’re gonna like, whether you like it or not.” The proclamation in the press ads for the New York Dolls’ debut album acknowledged they were a hard sell.

The descending refrain opening the song isn’t unusual but attention is instantly attracted as it’s played on a harpsichord. Equally instantly, an elegiac atmosphere is set. The voice, coming in just-short of the 10-second mark, is similarly yearning in tone. The song’s opening lyrics convey dislocation: “You and I travel to the beat of a different drum.”

A reissue can be an aide-mémoire, a reminder that a record which has been off the radar for a while needs revisiting, that it deserves fresh attention.

One of last year’s major joys was the box set version of Hawkwind's Space Ritual, an 11-disc extravaganza which made the great live album, originally issued in May 1973, even more great. Now the two studio albums which preceded it – X In Search Of Space and Doremi Fasol Latido – have become similarly packaged, though less colossal, box sets.

The return to shops of a consecutive sequence of five of John Cale's Seventies albums through different labels is undoubtedly coincidental. All have been previously reissued multiple times and none are scarce in any form. Anyone wanting any of these albums presumably already has a copy. Nonetheless, it’s good that these makeovers sustain the profile of Cale’s idiosyncratic take on art-rock.

“Let's walk down memory lane the Magazine way. Let's regurgitate fifth-rate Low [the David Bowie album] period pieces. Let's plonk plonk plonk with ponderous sub-Pink Floydery. Let's do the wallpaper waltz. This is not pushing back the barriers. It's frighteningly bland conservatism.”

Tucker Zimmerman is singing a number called “Don’t Go Crazy (Go in Peace)”. At 83, he performs sitting down. Surrounded by support band Iji, who act as his pick-up, he approaches the song in a whispery, affable voice. At the start of his set he was assisted to his seat but, knees aside, he’s not frail. He’s just laid back, a Sixties original, strumming gently. “Don’t go crazy,” he sings, “Go with the flow, go in peace.” Although he’s advised us to not think about politics, it’s hard not to.
