The girl who stole Johnston's heart, Evyn, later became his wife. He told ET Online
the story behind this southern rock love ballad. "I'm a very lucky fella; not many people get to be with a woman like mine," Johnston said. "I fell fast and hard. I remember thinking it was kind of like being struck by lightning. The hair on the back of my neck stood up, and I got the shakes the first time I saw her. When I wrote 'White Lightning,' I sat down and put that experience into this song the best way I could."
