Enter Sandman by BruceM

Question 12

Two answers required. On Halloween night, 2017, a superstar drummer/singer guest-hosted for Jimmy Kimmel. An actress appearing on the show that night sang "Do You Want to Build A Snowman?" and segued into "Enter Sandman." Name both the musician and the actress who teamed up for that medley.

The former was in Them Crooked Vultures (among other bands), a trio with Josh Homme and John Paul Jones. Meanwhile, Diana Tremain is the alter ego -- and the name that had appeared on the fake ID -- of a dead but rapidly maturing Phoenix native played by the latter.

Dave Grohl; Kristen Bell
