Garth Brooks (b. 1962) was the guest star on Muppets Tonight episode 102. In this episode, he announces that he doesn't want to do the same ol' Garth Brooks material, and wants to branch out -- playing Romeo to Miss Piggy's Juliet, impersonating Tom Jones, and performing as Tevye from Fiddler on the Roof. At the end of the episode, Brooks takes pity on the frazzled Clifford, and performs a rousing Garth Brooks song, "We Shall Be Free".
On Sesame Street, Brooks sings "Two Different Kids" with two Anything Muppet kids (EKA: Episode 3187), and "Together, We'll Make Music" with Herry and the monsters. (EKA: Episode 3849) The latter segment appears on Kids' Favorite Country Songs. He also sings in the celebrity version of "Sing" on episode 3851.
Brooks, and one of his most popular songs, were spoofed as "Friends with No Faces" by Dr. Bunsen "Garth Honeydew" in a Jim Henson's Muppet Trading Card.
