Legendary rocker Neil Young pledged $100,000 to Vermont’s legal bid to label all food products that contain genetically modified organisms (GMOs), urging other wealthy donors to back the state’s prolonged legal battle with food industry advocates.

“I’m just a rock ‘n’ roller who believes people should know what they’re eating,” Young said during a press conference in Essex Junction Sunday evening, local NBC affiliate WPTZ reports. Young appeared alongside Vermont governor Peter Shumlin, who said the rocker had called him “out of the blue” 10 days earlier to offer his support for the campaign.

A coalition of food industry representatives, led by the Grocery Manufacturers Alliance, have attempted to overturn the law as “a costly and misguided measure.”

Young previously called on Starbucks customers to boycott the coffee chain for its alleged support of the lawsuit, a claim the company promptly denied.
