Elvis Presley? PAL Hop rockers? Keystone cops?

Three months ahead of this year’s Great Falls Balloon Festival, clues are starting to emerge as to this year’s theme.

“We are sooooo excited we cannot keep it a secret any longer!” screeched a Wednesday morning post on the festival’s Facebook page. “Live, on the main stage Saturday night, August 18 — A PAL Hop Reunion! The Travelers and The Rockin’ Recons will be performing. Mark your calendars — don’t miss it!”

An image posted on the page reveals the theme “Rock around the Park” for the festival, slated for Aug. 17-19.

Additional images of Keystone Cop-shaped balloons appeared with the declaration: “Keystone Willy and ConAir will also be joining us! Watch the skies for Willy chasing ConAir!”

A little farther down the page, a photo of a balloon in the shape of The King himself.

“Elvis will be here!” festival organizers promised.

An official calendar of events was not available Wednesday.

With an estimated 100,000 people attending the festival each year, organizers say the event brings more than $2 million into the Twin Cities — 73 percent of which comes from outside Lewiston-Auburn.
