After Judy Dyble left Fairport Convention in May 1968, it was her replacement Sandy Denny who picked up critical kudos as the ensuing years unfolded. Dyble, though, did not drop off the face of the earth and, if credits were looked at closely enough and margins examined, it was evident she had a career in music as fascinating and often as admirable as that of Denny. Widespread consideration of her role in British folk and folk rock began after the issue of her album Enchanted Garden in 2004. Before that, Dyble’s last commercial release had been in 1970.

 It’s one of the greatest rock songs of the Seventies. The production is dense and the churning guitars are thick with tension. Beginning with a minor-key riff suggesting a familiarity with The Stooges’ “No Fun”, the whole band lock into a groove which isn’t strayed from. The tempo does not shift. Rhythmically, this forward motion has the power of a tank stuck in third gear. The voice suggests John Lennon at his most raw. Two squalling guitar breaks set the Jimi Hendrix of “Third Stone from the Sun” in a hard rock context.

There's something reassuringly resistant to modernity about Jeff Lynne. In much the same way that his cast iron Brummie accent and demeanour have remained unchanged despite decades in Los Angeles, so his music remains in a late 20th century interzone – its real concerns being the songwriting of the Sixties and the huge, glossy production values of the Seventies and Eighties.

“A huge lizard in sunglasses” was Robin Askwith’s impression of Pier Paolo Pasolini on first meeting the Italian director.

Little Bob Story: Off the Rails + Live in ‘78

Paul, Jan and Louis, three young men living in a gritty part of south London, are bored and broke and, for them, there are two kinds of Britain – one with money and power, and the one they live in, with no money and little to look forward to. No, it's not a play set in 2015, but Barrie Keeffe's Barbarians, set in the mid-1970s when youth unemployment was at an all-time high and the pound was at an all-time low.

Faces: You Can Make Me Dance, Sing or Anything… 1970–1975

There’s no sign of Oldenburg, Warhol or Lichtenstein and British pioneers Eduardo Paolozzi and Peter Blake are notably absent from this gritty vision of Pop art. Only in the final room do we come face-to-face with a Campbell’s Tomato Soup tin, the comforting bright colours and clean, supermarket-aisle lines blackened, singed and fragmented as if salvaged from some unimaginable disaster.

Pere Ubu: Elitism for the People 1975–1978

Turning autobiography into comedy gold is an alchemy that has often been tried. Among them Caitlin Moran’s Raised by Wolves, Kathy Burke’s superb Walking and Talking, and the mooted but, as yet uncommissioned story of Jeremy Clarkson’s childhood, provisionally titled For Whom the Bellend Trolls.
