A few hours before Neil Young sang a note on Sunday night in Essex Junction, he put his money where his mouth was about to go. The rock legend pledged $100,000 toward Vermont’s legal bills to defend the state’s GMO labeling law.

“I’m just a rock ‘n’ roller who believes people should know what they’re eating,” Young said at a backstage pre-show press conference with Gov. Peter Shumlin. Then he upped the ante.

“We would like to see some of the high-rollers in Vermont who believe in this come up and match that, ’cause if you’ve got it, break it out,” Young said. “Remember, this is a big, multinational group of corporations working together to make sure you don’t know what you have on your food table.”

Young is on tour promoting his latest album, The Monsanto Years, which is one long musical slap at the pro-GMO seed manufacturer.
