An eye: a white pupil burning at dead centre, a blush (F) and spring green (A) iris, grey-blue lashes at the rim. The percussion, barely a mark across the first quarter, floods in as the gospel arrives, 5,000 voices gathered from his own audiences, and at the loudest, most crowded moment the wobble drops to its lowest reading of the entire song. The crowd arrives and the harmony exhales. The image is the witness. It's with you.
