Broken leg aside, Dave Grohl‘s had pretty much the most fun year imaginable. He’ll cap off 12 months of touring and rejoin some old friends on December 1 with an appearance on The Muppets‘ gritty reboot on ABC, according to Variety. He’ll battle the Muppet Band’s gruff-voiced puppet percussionist Animal in a drum-off on an episode that’ll also feature Joseph Gordon-Levitt singing a duet with Miss Piggy on her late-night talk show. Yeah, this version of Jim Henson’s show is even weirder than the last time Dave Grohl played with them.
