Radiohead frontman Thom Yorke performed a new song, "Plasticine Figures," for the first time on Wednesday's
Tonight Show. If you've only heard the word "plasticine" in the lyrics to the Beatles similarly enigmatic "Lucy in the Sky With Diamonds" and are not sure what it means, it is a form of modeling clay commonly used by children. The main characteristic of plasticine figures, Yorke suggests, is their malleability. You can try to figure out whether that's a good or bad quality.
And if you want to figure out the song to perform at your home, well, Yorke is happy to oblige.
