More Proof That Dave Grohl Is The Best Human On The Planet

10-year-old Nandi Bushell challenged Foo Fighters' drummer Dave Grohl to a drum-off, so he decided to write her a theme song for round two.

Every superhero does need a theme song, and this one by Grohl (featuring the Grohlettes) is perfect for Nandi. We can't wait to see what she's going to come back with. With she write an anthem for Grohl? We can only hope.
