Stadium Lights

I was at a concert. A song played. We turned our phone flashlights and waved them, And as I looked across the stadium, I saw three lights bouncing a certain way. I started bouncing along with them, And we were bouncing together. I looked somewhere else in the stadium, And I saw that three more lights Had started to bounce. We were bouncing together. I don't know who you are. But you saw me. And I saw you. We were bouncing together.
