 SYNC: When Rizzo comes in and whispers something to Kermit during  the shoemaker and the elves story, it is obviously not Rizzos  voice. This is because Steve Whitmire (qv) was already performing  Kermit in this scene. The Muppets typically use this method of  substitution and then dub in the correct voice later, but it appears  they overlooked this instance. The voice is almost certainly that of  Dave Goelz (qv).
