THE 2017 Waterhole Rocks will be Elvis-themed to mark 40 years since the King of Rock 'n' Roll died.
The music starts on Thursday morning at the Nanango Showgrounds with a pig-on-the-spit for dinner and tunes by the Rock and Roll Boys.
"They're from Gympie and they're really good,” event co-ordinator Terry Mackrell said.
Friday starts early at 8am with dancing classes and music until about 6pm.
The big acts for the night include Bully Guy, Tina and Joe and the South Burnett's own Elvis impersonator Jeff Hancox.
The special guest is The DJs who performed as the backing band for Johnny O'Keefe when he was tearing up the Australian rock 'n' roll scene.
"He just lived rock 'n' roll,” Mr Mackrell said.
Saturday will include more dancing classes, while the Mystery Car Cruise will depart the Nanango Showgrounds at 9am.
The fashion parade starts at 5pm and is expected to be hotly contested.
"We have an on-site make up and hair stylist and there are some really good prizes,” Mr Mackrell said.
The dancing will continue through to about 11pm.
Jeff Hancox will open the proceedings on Sunday morning with performances from Elvis' gospel catalogue.
Entry is free on Sunday, and events include the show and shine plus more music and dancing.
