I was stopped, waiting for traffic to pass so that I could make a left-hand turn. I heard nearby thunder. It passed me by in the form of a camouflage-painted jeep which had all kinds of outdoor gear and cycles attached to its top and back end. The thunder was actually John Lennon belting out "Give Peace a Chance" so loudly that I could understand the words when the jeep was a half a block away.
Maybe the louder we sing about peace and the more we offer our music to anyone around, whether they want it or not, the higher the chances we really will have peace in our world.
Or maybe the guy driving just likes the song.
A lot.
