Dave Dudley, best-known for his 1963 signature hit "Six Days On The Road," died on Monday of an apparent heart attack. The song brought Dave his first Top 10 and, along with another tune, "Truck Drivin' Son-Of-A-Gun," helped him earn an enduring reputation for truck-driving songs. Sawyer Brown had a country hit with "Six Days" in 1997. Our condolences to Dave's family.
