From the wiki: “‘Six Days on the Road’ is an American song written by Earl Green and Muscle Shoals Sound Studio songwriter Carl Montgomery, made famous by Country music singer Dave Dudley. The song was first offered to Louisiana Cajun singer Jimmy C. Newman but he turned it down. Paul Davis (not of 1970s ‘I Go Crazy’ fame) was the first artist to record the song, and Billboard magazine first mentioned this original version in September 1961 although Davis’ recording would have no chart impact.
