This is SO FREAKING AWESOME I can barely see straight to type this!!!
One of the things that has excited me the most about the Muppet renaissance of the last five years is the full-force return of beloved elements like The Electric Mayhem - they sounded fabulous on A Green and Red Christmas and absolutely NAILED this classic TMM song (on Jimmy Kimmel Live no less! I can't believe how kind Jimmy and his people are to the Muppets! He even interviewed Big Bird! BIG BIRD, I tell you!!!).
I'll echo earlier praise for Bill Baretta as Dr. Teeth (he HAS that character now, no doubt about it) and also give props to Matt Vogel as Floyd and Eric Jacobsen as Animal (that drum battle with Travis Barker was a riot, especially the ending - I wonder how they staged that!)...I'm with Dwayne1115 that "Janice sounded off" but hey, we've got the Mayhem back, I'm more than willing to be patient with whoever's voicing her now. (David Rudman?)
Bottom line...this continues the trend of wonderfully-creative uses of the Muppets to promote the home release of the new movie, rather than just having one of them show up and do a basic plug...Am I happy? POSS-A-LUTELY!!!
