Maybe you've got to be on American Idol before you get to Lambeau Field.

So Will Makar now realizes. The good-natured former contestant on the FOX reality show says he kept calling the Green Bay Packers for years, saying: "I want to sing for you guys!"

On Thursday night, he'll finally get his chance.

The pop-jazz vocalist will belt out the national anthem to open the Packers-Vikings game in Green Bay.

"I definitely am so excited for singing there," he said.

Makar's fans in Oshkosh couldn't be more proud.

"What's so funny is, Will was born and raised in Houston, but my brother's from Wisconsin and is a big Packers fan," his autn, Anna Sundet, said. "Will just thinks the world of Brett Favre."

Earlier this season, Kelly Clarkson sang the national anthem before a Dallas Cowboys home game.
