Stephen Joseph Hardin was an American songwriter, keyboardist, and harmonica and clavinet player. He was probably best known as the writer of top-ten country hits "I Love My Truck" and "Breakin' Down", although his diverse career included performing tours with Point Blank, Glen Campbell and Steppenwolf; a seven-year gig in a south Florida Reggae band; and a solo CD with backup vocals by Gretchen Wilson.
