What is it exactly about Kermit, Gonzo, Miss Piggy, and Fozzie Bear that makes me want to tap my toes? Two years ago, I heard whispers that an album of Muppet cover songs was happening. At the time, it was called The Muppets Remastered—it’s since been changed to The Green Album. And today it is finally out. My favorite song is definitely Andrew Bird’s cover of “It’s Not Easy Being Green.” But Weezer and Hayley WIlliams’ “The Rainbow Connection” is pretty sweet too, as is Matthew Nathanson’s “I Hope That Something Better Comes Along.” As Slate notes, however, there is one oversight—what happened to “She Makes Me Happy,” Kermit and Miss Piggy’s wedding song from “The Muppets Take Manhattan”? But hey, it’s still pretty thrilling.
