If you’re of a certain age, you probably have a kid that loved the Disney movie Frozen. There’s many of you that probably liked and still like Metallica. Dave Grohl is one of those people, and guest-hosting Jimmy Kimmel Live! last night, the Foo Fighters frontman, dressed as David Letterman, performed the film’s “Do You Want To Build A Snowman” with Kristen Bell. Bell, who sang the song in the movie, was dressed as Magnum P.I., and started to do the song while Grohl, fake beard and all, gesticulated wildly. However, he quickly got behind the drum kit and with the help of Kimmel’s band, rocked the song, then segued into a cover of Metallica’s “Enter Sandman.”
