Keith Urban released a video for his latest hit Wild Hearts. He tipped his hat to Johnny Cash at the start of the tune. Cash’s was the first concert that Urban saw at age 5, brought there by his father. He wanted to trace the start of his career with the tune, and actually got permission from the writers of Wild Hearts to change some of the lyrics to better suit his story. The boombox at the start of the video represents the beginning, when he had no band and just played to a couple of people.
