Jack Black was a guest on The Graham Norton Show on Friday, and he showcased his incredible voice by giving the audience a taster of the theme tune he and Nick Jonas cooked up for the new Jumanji film.

He sang in classic rock-operatic Jack Black style, and somewhere far away, Kyle shed a single tear.
