Kermit the Frog won't win the Grammy this year, but he's moved into covering some more recent, adult tunes. This will be amusing only if you're familiar with the song (and only of marginal interest to your kids), but I swear that if you are familiar with it, you must must must watch this all the way through. (Hat tip: Idolator.) I'm not a huge fan of this song , but the album it closes, Sound of Silver, is pretty awesome.
And if you're not familiar with that song, you can always go back and watch this more familiar cover.
