THE heat at Parkes would be enough to get most people all shook up, but for hundreds of Elvis impersonators it was a case of burning love.

The five-day Parkes Elvis Festival in NSW, which wraps up today, is now in its 21st year, with about 18,000 people flowing through the gates to celebrate all things lycra, Brylcreem and bacon.

President of the festival committee, Gail Bartley, said soaring temperatures had been trying, with 45C heat and rhinestoned onesies not a match made in heaven.

But she said the slew of Elvis impersonators at the festival were willing to suffer for their art.

"You've got to give it to the boys," she said.

"They really go above and beyond in the name of Elvis."

Over the festival's five days, punters were treated to more than 150 events, including an Elvis gospel church service, Elvis street parade and the Crowning of Miss Priscilla.

For loved-up Elvis lovers, there was even an Elvis wedding chapel on site for couples to renew their wedding vows, complete with an Elvis celebrant.
