"All Hail to Massachusetts", with words and music by Arthur J. Marsh, was made the official state song of Massachusetts on September 3, 1966, and codified by an act of the General Court in 1966. In 1981 the General Court amended the act to include the song "Massachusetts", words and music by Arlo Guthrie, as the state's official "Folk" song.
