Lee Byberg, the Republican candidate facing longtime Democratic U.S. Rep. Collin Peterson, will get a boost from the singer of the campaign-ubiquitous "God Bless the USA" song next month.

Lee Greenwood, whose song rings out from speakers at parades and rallies across the nation, will join a Byberg "Northern Lights Freedom Chorus" event in Alexandria on October 21.

The Freedom Chorus, there are two before the Greenwood-headlined one, "is a citizen mega-choir that will enable communities and neighbors to join together and sing traditional hymns and patriotic songs about America....It's designed to unite the district, uplift America, and generate enthusiasm heading into the November election," Byberg said in an email to supporters.

The singing events continue a trend of unusual campaigning from Byberg. He also put out a bio book in which he reflects "upon the values principles which made American the greatest country ever seen."

Byberg's campaign might need the lift. As of his last campaign finance report, he had $91,921 cash on hand and $120,370 in debt. By contrast, Peterson had $799,953 and no doubt.

Byberg and Peterson faced off in Minnesota's western congressional district before. In 2010, Byberg netted 38 percent of the vote to Peterson's 55 percent.

And, for something different, here's Beyonce performing Greenwood's signature song:
