Let's have a little bit of Muppets. You know this song, "C is for Cookie," but it's not from who you think. Nope, this is from legendary opera star Marilyn Horne. And they go all out and give it the full dress extravaganza. It has an arrangement and production that takes a little Sesame Street ditty and ratchets it up to something out of Verdi's Aida. To Marilyn Horne's credit, she throws herself into it all the way. But then, she often like to have fun at the expense of her refined, sophistated career, often appearing on A Prairie Home Companion.
