The sideburned, hip-swivelling sexiness of Elvis Presley spawns more fans, impersonators and memorabilia every year.

Whether it's due to the sexy moves, his status as the world's most famous rock 'n' roller or his fun-lovin' sense of humour, there's no denying the enduring, enigmatic appeal of The King.

His songs still fill the airwaves, his face graces postage stamps and velvet paintings, thousands trek to his home Graceland (second only to The White House for visitor numbers) to pay homage every year and even academics hold international conferences on him.

Especially predominant are the leagues of Elvis impersonators - from the uncle who dresses up at Christmas to professional performers who make it their living.

There is a US National Association of Amateur Elvis Impersonators, a Las Vegas Professional Elvis Impersonators Association, and even a troupe of lookalikes called the Flying Elvi (plural of Elvis), who jump from 13,000 feet dressed as the man.

Twenty years after his death in 1977, there was a seven-day festival with 35,000 impersonators from around the globe - a number which probably only scratches the surface of the ever-growing quantities of Elvi around.

"Something happens when I hear Elvis music," sighs Hove-based Presley appreciator Lou Acford. "Especially when a hunk of a guy with black hair and an open shirt sings it looking straight at you."

"It's the hu hu's, the shakes, the music, the moves," says local Elvis fan Katy Dolt. "He was the first really cool person ever - and he's timeless. Most stuff fades over time, whereas his music just keeps getting better. Are we going to see Elvis impersonators in Brighton soon? Please can we?"

Right on cue comes Brighton-based and nationally renowned impersonator Ivor Potter's show One Night In Vegas.

Complete with casino, palm trees and Memphis Mafia security, the idea is to re-create the feel of the infamous Elvis in Vegas nights of the early Seventies when The King was at the height of his reign.

Showgirls meet guests at the door and hand them a Monopoly-style £50 note to gamble with at the blackjack and roulette tables, the crowds dress up in rock 'n' roll gear and Presley memorabilia is on sale.

With characteristic lip curl, Potter takes the audience through old favourites such as Jailhouse Rock, Love Me Tender and All Shook Up with his band Undercover.

Before embarking on his current career path, which supplements his degree course at London's Mountview Theatre School, Ivor was a builder.

Unlike many impersonators, Ivor is not a manic Elvis fan. He doesn't spend endless hours listening to the records in his bedroom or preening his hair into a quiff.

He has an agent and studies acting in London to perfect the Southern US accent but he peels off his Elvis sideburns at the end of the night.

"I've watched the shows and read the books," he says. "I like his music and we have great fun doing the shows but I don't live and breathe it. I leave that to the fans."
