It's not quite a new episode of The Muppet Show, but this performance of the Willy Wonka classic "Pure Imagination" is a perfect blend of Muppet sketchwork and actual song — starring Josh Groban, violinist / YouTube star Lindsey Stirling, and a cavalcade of puppetry.

The video is a high point in a collaboration between the Muppets and YouTube Space LA, wherein the iconic characters guest star on other popular channels like Mental Floss and Mike Tompkins. We've collected some of our favorites below (here's the full playlist), but seriously, this "Pure Imagination" cover is 100 percent joy.
