In the song “Sweet Dreams”, Eurythmics sang, “Sweet dreams are made of this. Who am I to disagree? I travel the world. And the seven seas. Everybody’s looking for something.” And in the song “Happy”, Pharrell Williams sang, “Because I’m happy. Clap along if you know what happiness is to you.” So Stephen paints about the different versions of happy. Like in the quadriptych (4-piece) “What a Wonderful World”, he painted for his hopelessly romantic mother her version of “content” to see the baton passed to the next generation.
