When you can't stop them ... sing over them. That's what the alternative rock band Foo Fighters did when the Westboro Baptist Church decided to stage a protest against the group. 

On Friday, protestors from Westboro Baptish Church planted themselves outside of a Foo Fighters show in Kansas City, Mo. to protest the band for promoting fornication, adultery, idolatry and homosexuality with their music.

In response to their protest, members of the alterntive Foo Fighters band, sporting costumes they wore in a recent video parody, jumped onto a flatbed truck, parked across the street from the protest, and played an impromptu show. The band performed Keep It Clean (Hot Buns), a song about intimate relations between two men, CNN affiliate KSHB reported.

The lyrics to the song go: Driving all night, got a hankering for something/Think I'm in the mood for some hot-man muffins/Mmmm, sounds so fine, yes indeed made a pointed response to the church's protest.

I don't care if you're black or white or purple or green, whether you're Pennsylvanian or Transylvanian, Lady Gaga or Lady Antebellum. It takes all kinds, said Dave Grohl, the Foo Fighters frontman.

As they often do, the protesters held up brightly colored signs that read, God Hates Fags, and Thank God for Dead Soldiers.

Grohl ended the song with a patriotic message: Ladies and gentlemen, God bless America! Land of the free, home of the brave, KSHB reported.

In a news release, dated August 30, 2011, the church said it would protest the Foo Fighters concert because The entertainment industry is a microcosm of the people of this doomed nation: hard-hearted, Hell-bound, and hedonistic to the max. Every person with a platform should be using it to encourage obedience to God; instead, you teach all things contrary to Him: fornication, adultery, idols, fags.

The Kansas-based Westboro was started by Fred Phelps in 1955; it is best known for protesting soldiers' funerals. The church's membership is small and mainly comprised of Phelps family members.

The Foo Fighters performance went viral over the weekend. The band posted a behind-the-scenes video on YouTube of preparations play on the street in front of the church that has racked up nearly a half a million hits.

A representative for the Foo Fighters told CNN, The band is leaving that video/performance as their only comment on the matter.
