When it was issued in May 1968, “Fading Yellow” attracted no attention. It couldn’t have as it was the B-side of “Mr. Poem”, Mike Batt’s poor-selling debut single. The top side was good, very 1968 and along the lines of whimsical 45s like Donovan’s “Jenifer Juniper” or Marty Wilde’s “Abergavenny” but wasn’t a hit. Relegated to the flip, “Fading Yellow” was obviously considered the least commercial of the two songs.

A work of genius isn't sacred, copyrighted territory. A great film may become a play, a novel a film; the adaptation shouldn't be about fidelity, as Elena Ferrante has written about the latter case, but down to to the director "to find...the language with which to get to the truth of his film from that of the book, to put them together without one ruining the other and dissipating its force".

Dennis Hopper’s first starring role, in Night Tide from 1961, as a naïve but curious young sailor bewitched by a siren, offers a strange mirror to his role as the evil Frank Booth in David Lynch’s Blue Velvet (1986). If anything, he offers a preview of the bemused Jeffrey Beaumont played by Kyle McLachlan in Lynch's masterpiece.

In July 1961, the first issue of the Liverpool music paper Mersey Beat put three items on its front page. One was a surreal article by John Lennon titled Being a Short Diversion on the Dubious Origins of The Beatles.

As one decade gives way to the next, the beginning or end of the ten-year cycle rarely yields anything cut and dried. With pop music, a host of decade-related platitudes have no respect for the decade-to-decade switch. Depending on points of view, the Sixties didn’t begin until 1962, 1963 or 1964. With the Seventies, the kick-off could have been 1971 or 1972. Or maybe 1976 or 1977.

Earlier this year, the Peter Laughner box set was more than an archive release. Its diligence and scale forced a wholesale reinterpretation of the evolution of America’s punk-era underground scene. What it collected – aurally and in its book – demonstrated Laughner was more of a pivotal figure than he had so far seemed, and that his actions and vision resonate more than four decades on from his death.

Hugh Hefner established Playboy Records in 1972 as an arm of his male-targeted business empire. Amongst the singles issued in its first year were seven-inchers by jazzer Bobby Scott, proto-yacht rockers The Hudson Brothers, singer-songwriter Tim Rose, Björn & Benny (with Svenska Flicka), who were ABBA before they had a name, and Michael Jarrett, who’d written “I'm Leavin'” for Elvis Presley. In 1974, Playboy Playmate Barbi Benton came on board.

Inua Ellams’ Three Sisters plays Chekhov in the shadow of war, specifically the Nigerian-Biafran secessionist conflict of the late 1960s which so bitterly divided that newly independent nation.

“I was just released from the hospital…the doctor told me that the medicine can’t do me no good. They told me what I have is beyond medical science…he told me that what I have is more serious than cancer. He told me what I have is a very, very bad case of the blues. I found out the best remedy for the blues is to be with the one you love.”

If the prices fetched by original pressings are a guide, Mighty Baby are notable. Their eponymous first album, issued by the fittingly named Head label in November 1969, sells for at least £150 and has changed hands for over £500.
