Foo Fighters and Heart's Wilson Sisters 'Kick It Out' on 'Letterman'

Foos will also debut new single at a Chicago concert that will be livestreamed via HBO's Facebook

One night after busting out a Black Sabbath cover with Zac Brown, Foo Fighters continued their Late Show With David Letterman residency by paying homage to the city Dave Grohl is most associated with: Seattle.

With the Space Needle projected on a large screen behind drummer Taylor Hawkins, the Foo Fighters welcomed Seattle rock royalty, Heart's Ann and Nancy Wilson, to the stage for a rendition of their Little Queen single "Kick It Out." Grohl stood mostly in the background this time around, letting the Rock and Roll Hall of Fame sisters do their thing. "Good God, we should do this every night," Letterman shouted following the performance. "Every night it's a party."

While Tuesday's Late Show didn't feature Grohl sitting on Letterman's couch again, the late night host did accidentally set off the show's new "Foo Signal," which was installed because the Foo Fighters will be spending all week with Letterman in support of their upcoming HBO series Sonic Highways. Once the Foo Signal was triggered, the band came running out from backstage to see if Letterman was in desperate need of assistance, but thankfully it was just a false alarm.

If five nights of Letterman performances and the premiere of Sonic Highways isn't enough Foo for you, HBO also announced that immediately following the series' first episode on October 17th, the band will perform a concert at Chicago's The Cubby Bear that will be livestreamed via HBO's Facebook page. This performance will also feature the live debut of "Something From Nothing," the first single from Sonic Highways. According to the Hollywood Reporter, Grohl opted to visit the Cubby Bear because the Wrigleyville club was the venue where he witnessed his first punk rock show. The opening episode of Sonic Highways will similarly focus on Chicago.
