Who performed the character with which  Ozzy Osbourne sang "Born to be Wild" in the music and comedy record "Kermit Unpigged"?
Kermit Unpigged Kermit Unpigged is a music and comedy record released by The Jim Henson Company through BMG Kidz in 1994, and the last album released by Jim Henson Records. The record’s title is a clear parody of the MTV series “MTV Unplugged”, and the cover is a parody of Eric Clapton's "Unplugged" album cover as well. The album consisted of Kermit and the other Muppets getting lost at a recording studio and encountering celebrities including Linda Ronstadt, with whom Kermit sang “All I Have to Do is Dream”, Vince Gill who sang “Daydream” with Kermit, Jimmy Buffett who sang “Mr. Spaceman” with Gonzo, and Ozzy Osbourne with whom Miss Piggy sang “Born to be Wild.” The album ends with all The Muppets meeting back up and singing the Beatles song “All Together Now.”
