Before Sesame Street, SNL, or The Muppet Show, Jim Henson’s Muppets appeared on The Ed Sullivan Show in 1968 to perform a song called “Sclrap Flyapp”. Sclrap Flyapp eventually evolved and became “Hugga Wugga” on The Muppet Show. I’ll include both below for your viewing pleasure, but I prefer the original!
