We all know Stevie Wonder is a musical genius and clearly only a genius can just make something up off the top of their head and turn it into a whole song. Stevie Wonder did just that. He broke out in song at an event and got the audience involved with a catchy tune that encouraged everyone to vote.
The beat is everything, and when you couple that with the words he's saying I would be up singing and clapping too! Must be nice to just think of a song in your head and the band just jumps in and starts playing. Love it. And go vote.
