Witness ​Dave Grohl Dress Up as David Letterman and Mash Up Metallica with Disney's 'Frozen'
As promised, Foo Fighters frontman Dave Grohl hosted Jimmy Kimmel Live! last night (October 31), and partook in some Halloween fun.
 
He hosted the show sporting a hilarious David Letterman costume, and took his task of interviewing guest Kristen Bell to the next level. After revealing that his kids are mega-fans of the Bell-voiced Disney smash Frozen, he attempted to gain some cool dad points by jamming with the IRL Anna.
 
Putting a spooky twist on the Frozen soundtrack's "Do You Want to Build a Snowman," the duo and the show's house band mashed it up with Metallica classic "Enter Sandman."
 
It's absolutely as ridiculous as it sounds, and you can check it out below.
