Dave Grohl and his daughter Violet Grohl did an acoustic cover of Adele's "When We Were Young" during a benefit concert in Oakland, California Saturday.
Right afterward, Grohl's younger daughter Harper came to the stage to play drums and Violet sang backup when their father played Foo Fighters' "The Sky Is a Neighborhood."
This two kids are AMAZING. (no surprise as DAVE GROHL's spawn!)
Then Violet finished up on lead vocals and Harper on drums as the Grohls covered Queen's "We Will Rock You." Grohl's daughters previously appeared in the Foo Fighters' "The Sky Is a Neighborhood" video.
