Gotta Get That Name

From Muppet Wiki

"Gotta Get That Name" was sung by Kermit the Frog, Miss Piggy, and the cast of the Rumplestilskin segment of Muppet Classic Theater as they try to figure out the name of the title character (as portrayed by Gonzo), listing many names and asking him if any of those those are his name. Needless to say, they don't figure out the name until after the song is over.
