MUSKOGEE, Oklahoma - The June heat is wearing on music fans attending Muskogee's first ever G-Fest.

More than 80 acts will play on four stages at Love-Hatbox Field – an old World War II airfield. And people from all over the country have come to see the show.

Hometown favorite The Swon Brothers were one of the G-Fest headliners and took the state Friday. They said it’s a lot of pressure seeing familiar faces in the crowd.

"Whether it's this stage or the Muskogee State Fair that we played when we were kids, you know it doesn't matter, these people have supported us. Whether it's ten people or 10,000, we'll always come back and play our hometown," Zach Swon said.

The brothers are touring across the country with another Oklahoma native, Carrie Underwood.

Colton Swon said he believes G-Fest will become a popular festival.

"This is a big deal for Oklahoma,” he said. “Like, I'm telling you, we play festival after festival every year, and some of the biggest festivals that you can play, this is going to be one of those festivals," he said.

One group of fans drove from Colorado to see Colton and Zach play in Muskogee.

Madyson Buhring said, “It's awesome that their home, home. Yeah, it's cool."

"It's great. It feels great to see things happening for Muskogee. It's pretty awesome," Shannon Evans said.

The Swon Brothers even helped a military serviceman get engaged.

During their performance, the brothers invited John Staats, who serves in the U.S. Army, on stage where he proposed to his girlfriend, Amanda Davis.

Staats and Davis were volunteering as security guards and are both firefighters. Staats is about to be deployed with the Army.

G-Fest continues Saturday at noon with a special tribute to Merle Haggard, who was slated to be the headliner of the inaugural festival before his passing.
