Farm Aid celebrating 30th anniversary on Chicago's lakefront

CHICAGO (WLS) -- Farm Aid is celebrating its 30th anniversary on Chicago's lakefront this weekend.

Saturday night, Willie Nelson, John Mellencamp and Neil Young will be performing and the all-day music fest is completely sold out.

Country star Kacey Musgraves took to the stage at Northerly Island Saturday afternoon, one of the latest in a long line of artists who over the years have supported the Farm Aid movement dedicated to supporting family farms across the country.

Farmers like Greg Gunthorp from La Grange Indiana, whose family has raised pigs on pasture for over four generations.

"It helps to shape the future, education and awareness of consumers," he said. "More and more consumers are becoming appreciative of how their food is raised, how it's handled and how it's processed."

It's been 30 years since Nelson, Young and Mellencamp started Farm Aid in 1985. Saturday, a second generation of Mellencamps joined in.

"It's an amazing event," said Ian Mellencamp. "I attended it as a child. Now to be a part of it and actually playing music and contributed, it's phenomenal."

For the thousands of people in attendance, the opportunity to support a good cause while also enjoying a full day of great music is simply, the best of both worlds.

Imagine Dragons and Dave Matthews are also among the acts expected to perform Saturday night.
