"We do it because we feel like we’re standing up for what we think is right."

Foo Fighters’ summer of viral news continued this weekend when the band Rickrolled the Westboro Baptist Church at Kansas City’s Spring Center on Friday, as the Church picketed the venue where the band was due to perform.

Later that night during the show, Foo frontman Dave Grohl explained their reasoning. “You can’t just sit there and do nothing, you got to go out there, and say what you wanna say, so we did,” he said.

Grohl relayed the whole story: “Well, tonight we were sitting backstage, and someone said: ‘Guess who is coming tonight?’ And I said: ‘Who?’ They said: ‘Them.’ I said: ‘Why?’ They said: ‘Cause.’ And I said, ‘Cool, let’s go out and f–kin’ hang out with them for a bit.’ So we didn’t have enough time to put together the big old show that we put on last time, so we figured, you know what, why don’t we just fucking RickRoll their ass? Cause nothing says love like a little Rick Astley in your life, you know what I’m saying? Never gonna give his ass up!”

“Last time” refers to 2011, when the Church protested another Foo Fighters show in Kansas City. “So I’m going to dedicate this song to all the people who go out and speak their mind, to stand up for what they think is right, because every time we got to stand up in this city in front of them, we do it because we feel like we’re standing up for what we think is right,” Grohl said before launching into an emotional performance of the band’s hit song, “My Hero.”
