Arlo Davy Guthrie (born July 10, 1947) is an American folk singer. Like his father, Woody Guthrie, Arlo is known for singing songs of protest against social injustice. Guthrie's best-known work is "Alice's Restaurant Massacree", a satirical talking blues song about 18 minutes in length. His song "Massachusetts" was named the official folk song of the state in which he has lived most of his adult life.
