There have been some dark and moonless nights on the road, we all have them from time to time, when the land beyond the headlight beams is shrouded in uncertainty. You drive on deep into the countryside, that’s your only real option, and instead of falling into the bleakness of a nightly news bulletin, you listen to an old song on the radio. Then, in the distance, you see a twinkle. As you drive closer, it grows into a cluster of lights. You head for that.
