But in either case, the following version of the Appalachian folk tune by Buffy Sainte-Marie and a horse muppet whose name I do not know is entertaining for two reasons:
One is that it's an opportunity to see someone play an unusual instrument called the mouthbow, which sounds like a jaw harp, and about which you can find more info in an article entitled The Mouthbow: Making Music on a Weapon.
The second reason is that it's most likely the only time you'll hear a muppet sing the lyric:
"Now the girls up Cripple Creek about half-grown
Jump on a boy like a dog on a bone"
By the way, this song is not the same as the one that The Band made popular, even though the latter does include something that sounds a lot like a jaw harp, but actually isn't. You can find out more about that in the surprisingly informative clip that follows Buffy and the horse below:
