Despite temperatures soaring close to 40 degrees around mid day, the party crowd was not deterred.

Kim Dale travelled from Cowra with West Wyalong and Cargo mates. She said the lay out at the Escort Way Winery had made their journey in "easy."

"It's really, really well set up," she said.

"It's not actually as hot as what we thought it would be. It's just a really, really, great thing for Orange."

Sisters Kim Roughley and Belinda Houghton travelled from Orange with their friend Renee Rochester.

Mrs Houghton said she was looking forward to seeing Jimmy Barnes for the second time, having snuck into his gig at the Bathurst Panther's clubhouse about 30 years ago.

"Yep, I was underage," she said.

Mrs Roughley said she had grown up with her sister listening to Cold Chisel and had subsequently become a fan.

"I remember going into our room and rolling my eyes at Belinda like 'what is this music?'" she said.

Although the trio had chosen a position on the grass with "plenty of elbow room" 17-year-old Mrs Houghton was a little more ambitious.

"I was so close I got Jimmy's sweat on my watch band. I was never going to wash that off," she said.

Josh Maynard from Cowra opened the show with a 45 minute set just after 4pm.

He said he'd played another winery gig in Sydney of about 8000 people, so this was his biggest gig to date.

"The heats always draining, under those lights it's always very hot but you just make the most of it and wear your sweaty face," he said.

"It was brilliant."
