Five Muppet Gingerbread Men sing "Sweet Gingerbread Man" as the opening number in episode 201 of The Muppet Show.
The Gingerbread Man in the foreground is the lead singer and the only one who is a regular hand-puppet. The background singers, in contrast, are full-bodied Muppets without working mouths.
The lead singer was performed by Frank Oz, while the other four Gingerbread Men were performed by Jim Henson, Jerry Nelson, Richard Hunt, and Dave Goelz.
This was Oz's only lead singing appearance on The Muppet Show as a one-off character.
