SHAKE a leg, readers. Elvis is coming to Glasgow. Indeed, many Elvises are coming to Glasgow. In that sense, Elvis still lives, at least in a legacy of tribute acts based on love for the man and his music.

The Official Scottish Elvis Presley Festival celebrates the king of rock ’n’ roll with acts interpreting the great man’s performances at various stages of his career. These include Scotland’s Johnny Lee Memphis doing the On Tour era, England’s Simon Patrick covering 1969, and Germany’s Oliver Steinhoff interpreting 1970/71.

Unlike the man himself, alas, Elvis impersonation has shown remarkable longevity, clearly because the Mississippi-born singer tapped into something deep.

It was all before this writer’s time – though many of the performers look younger than do I – and consequently it’s difficult to grasp the revolutionary effect caused by a deep and tender voice combined with jungle drums and eye-popping gyrations.

Doubtless, it was all part of the post-war explosion of freedom from repressed attitudes and a desire to cut loose and enjoy life to the full. Disgraceful, really.

Youth culture was being born, and rockabilly provided the theme music for its first faltering steps. Despite his sexually provocative performance style, Elvis had a country-boy wholesomeness about him, not to mention a sense of patriotism, that must have confused the hell out of the older folks.

Then there was the fact that the tunes, as well as being catchy, dealt with important issues such as canine nihilism (You Ain’t Nothin’ But a Hound Dog) and the inadequacies of the postal service (Return to Sender).

Fame brought pressures on Elvis that were overwhelming, and it is hardly surprising he succumbed to the twin evils of drugs and peanut butter.

Neither of these, we trust, will pass the lips of this weekend’s performers, who also include Juan Lozano, Chris Kelso, Mario Kombou, Matt King, Ricky Aron and Gary Gibson. Let their legs give it laldy.

The Official Scottish Elvis Presley Festival is at the DoubleTree by Hilton Hotel, Cambridge Street, Glasgow, this Friday , April 7, to Sunday, April 9.
