The Cat (Sesame Street)

From Muppet Wiki

The Cat appeared in a Sesame Street News Flash based on the Hey Diddle Diddle nursery rhyme. He was the manager of Natalie, whom was going to perform a jumping-over-the-moon stunt. The Cat was also a professional violinist; he accompanied Natalie's takeoff with a fanfare on his fiddle and played Wild Blue Yonder as the cow went over the moon.
