There’s a lot of Seventies revivalism in the ether. Fleetwood Mac are back as a famous five after many years asunder. 10cc have on at the Albert Hall, although one astutely remarked that they really should have been billed 2.5cc. In When Pop Ruled My Life, the recent BBC Four documentary about fandom, it was lear that the Bay City Rollers are still very much a going concern. And this week it was announced that three titans of glamrock would stomp once again on British boards. They include The Rubettes, a band coyly billing themselves Mud 2 and – holy of holies – The Sweet.

To begin at the very bizarre ending. Fleetwood Mac, finally reunited as a five-piece with Christine McVie stage right on luscious vocals and keyboard, had just thrashed out a show of great finesse for two hours. It had all gone peachily. McVie was given a last lovely encore - “Songbird” – crooned solo on a grand piano. That should have been it. Many were already going, or gone.

Spooky Tooth: The Island Years (An Anthology) 1967–1974

Today, terrorism means killing as many innocent people as possible. Fear is created by completely random attacks, so that no one feels safe. But there was a time, in the past, when political anarchists would focus their attacks on selected targets and avoid civilian casualties. For a year, begining in August 1970, the Angry Brigade brought armed struggle to Britain, setting off some 25 bombs, mainly aimed at the property of the rich and powerful (although one person was slightly injured).

Dion: Recorded Live at the Bitter End August 1971

This latest Friday night vehicle for archive footage and pop performances was the tour bus, as BBC4 invited us to hop into the back of the van for a quick spin through the "golden age" of touring rock bands (which the producers clearly felt ended with the Eighties).

Fotheringay: Nothing More – The Collected Fotheringay

Rude Boy is a rotten film. Nonetheless it exerts an inexorable draw as it includes live footage of The Clash which is amongst the best of any rock group on stage. The performance of “Safe European Home”, caught on camera in July 1978, is white hot. That is, the performance as seen. The audio track was subsequently modified in a recording studio.

The Specials: Specials, More Specials; The Special AKA: In the Studio

Perhaps it’s because today’s economy often seems to reflect the nightmare of the late Seventies, but recent years have seen plenty of the original punks return to public attention with a renewed vigour. Whereas some, like support band The Rezillos, have reformed after a break of several decades, the Stranglers, despite a few line-up and stylistic changes, have never gone away and aren’t shy about playing a set of tunes drawn from their 40-year career.
