I Just Can’t Wait to Be… the Improviser! Charlotte begins playing a steady two-chord riff pulled from, “I Just Can’t Wait To Be King.” As Nancy improvises above the riff, her modeling sparks excitement and eagerness in Charlotte as she enthusiastically asks for a turn to improvise. “Can I try improvising?! …YES!” From Level 2A Showtime Piano, Pg. 4-5, “I Just Can’t Wait to be King.”
