They also pulled a Freddie Mercury lookalike from the audience at Leeds for a cover of "Under Pressure."
The Foo Fighters had a very busy weekend at the Reading and Leeds festivals in England on Friday (Aug. 23) and Saturday (Aug. 24), packed with special guests, touching tributes and their latest, greatest Rickroll. The flurry of activity kicked off on Friday, when Dave Grohl's 13 year-old daughter, Violet, hopped on stage to rock out with dad on "My Hero."
“This has been a special trip for me because on this trip we have a new Foo Fighter in the band with us,” Grohl told the audience at the show. "Let me tell you something—she is the best fucking singer I know... Ladies and gentlemen, the best singer in the Grohl family: Miss Violet Grohl right now, right here.” Father and daughter then blended vocals on the track from 1997's The Colour and Shape, coming together on the rousing chorus. Grohl threw his arm around Violet for a mid-song breakdown where he gushed about staying up all night watching horror movies and making sure the newest star in the family makes it to stage on time. (Stick around until the 7:20 mark to see the pair scream it out together.)
