Yoko Ono and Sean Lennon Sing An Anti-Fracking Song

You know fracking has established itself as the cool thing to protest when Yoko Ono performs a Bob Dylan-inspired song about it. The only way to take this up a notch is to collaborate with Neil Young. Ideally, this song would involve someone wearing a harmonica holder.
Yoko sang with her son, Sean Lennon, on Late Night with Jimmy Fallon. See the video below:
