The Martins, The Landmarks, Tupelo-Lee County Diversity Choir and the Foyer Boyz performed on the grounds of the Elvis Presley birthplace, underneath a huge tent. Attendees used Elvis fans to beat the heat.
Though gospel music was the event's focus, The King of Rock 'n' Roll was invoked a few times.
"How many of y'all would like to hear some Elvis gospel?" asked Brent Roberson of the Foyer Boyz. After getting a round of applause, he joked, "Us, too - anybody got a CD?"
A woman in the back shouted, "Sure do!"
In the crowd, decked out in a red and gold Elvis-inspired jumpsuit, was David Smock, 26, of Jonesboro, Ark. He and his mother, Vicki Pasmore, were in town for their third Tupelo Elvis Presley Festival.
"It's a lot better this year," he said. "We always want to go to certain events, but they may be sold out, but we always find more to do. There's always more than enough to do."
Smock has been an Elvis fan since he was 3 and makes his own jumpsuits by hand. The red one is his newest creation.
"It's devotion, I guess," he said, smiling beneath his sweaty mane of black curly hair.
Another Elvis look-alike received a ton of applause at the gospel show.
Kevin Mills, who won the Ultimate Tribute Artist Contest in Tupelo on Saturday, performed a few songs with the Landmarks to a standing ovation.
All four of the performers had the audience on their feet.
The Tupelo-Lee Diversity Choir sang rousing renditions of "Excellent" and "How Great is Our God," and were joined on stage by Kay Bain.
The Landmarks invited fans to sing along on songs like "Roll River Jordan" and "Standing in the Shadows."
Gospel group The Martins, who have toured with the Gaithers, shared Elvis stories and personal testimonies and received a standing ovation when they rounded out the three-hour show.
Festival director Debbie Brangenberg said the 2010 festival was a success.
"It was an outstanding weekend," she said.
Total numbers haven't been tallied, but she said she expects to see an increase in attendance from last year.
"I saw lots of smiles on people's faces," she said. "And that's what makes us do what we do."
