That song on every radio and wedding dj's playlist — that catchy earworm that's inescapable for an entire summer — the "song of summer." There's more to it than everyone knows. There's more to know about its singer, too, like why he snuck away from a concert and traveled hundreds of miles to visit the home of his childhood piano teacher. What — and who — he finds there could change his career and his life. The touching play The Song of Summer by Lauren Yee is about how revisiting the past can change our future.
