There was always a strong element of panto about Glam but Geordie took it one step further with this blatant send-up of Slade.

You can hear it in the sandpaper rasp of singer Brian Johnson and the football chants. And you can see it in guitarist Vic Malcolm’s knee-high silver stack-heeled boots, his high kicks, and his fringe.

They came from Newcastle, as if you couldn’t tell from the name and the Magpies shirt and scarf he’s wearing under those dungarees, and it will surely come as no surprise that they paid their dues supporting Slade.

In the small world of Tyneside rock, Vic’s previous band The Influence, had also included Roxy Music drummer Paul Thompson. I imagine Lindisfarne were somwhere nearby too.

There was more to Geordie than this terrace anthem – the B-side, for example, finds Johnson delivering a tight-trousered falsetto over some thunderous riffing, in an effort to emulate Led Zeppelin – but not enough to escape the relegation zone in a Glam league where T. Rex, Slade and Sweet competed for the Champions League spots.

Still, this atrocity reached a heady no.6, and they notched up an astonishing 15 appearances on Top of the Pops in the early Seventies.

I suspect if you’d told anyone at the time that the singer, a big lad who looks like his diet consists largely of brown ale, would be topping the charts half a century later you would have been laughed out of town.

Yet here he is, having been recruited to fill a dead man’s shoes in AC/DC some seven years after this, at No.1 in album charts all over the world this very week with the year’s fastest seller to date, Power Up.
