The carnival rides whirred on and fans hollered at the first concert of the festival, which featured Elvis tribute artist Kevin Mills and Sonny Burgess amp& the Legendary Pacers, featuring DJ Fontana.
"The rain gave us a bit of a break," said Debbie Brangenberg, festival director. "It'll really make a difference in temperatures. I think we'll have the best weather ever in the history of the festival."
Inside at the concert, fans from across the world - including places like New Zealand and England - lined up to see the band and the Elvis tribute artist. Most fans wore at least an Elvis T-shirt, and some also wore Elvis purses and jewelry.
Burgess kept fans entertained with old favorites like "Folsom Prison Blues," "My Bucket's Got a Hole In It," and "Wooly Bully."
The evening closed with a meet and greet and open mic with Elvis tribute artists.
Temperatures will stay in the mid-to-high 70s today for concerts by Paul Thorn and Jordyn Mallory at Fairpark, the first round of the Ultimate Elvis Tribute Artist competition and a concert by Tupelo's first ETA winner, Brandon Bennett. Bennett's sold-out show will be simulcast outside.
Saturday's high will reach the low 80s. The day begins with a 5k run, parade, final round of the ETA competition, and a show by last year's winner, Cody Slaughter.
Little Big Town, David Nail and Randy Houser will perform at Fairpark. Sunday there will be a gospel show at The Lyric, and tickets are still available for it.
"It's gonna be the best weekend ever," Brangenberg said.
