Josh: Voyager, in case it's ever encountered by extraterrestrials, is carrying photos of life on earth, greetings in fifty-five languages, and a collection of music from Gregorian chant to Chuck Berry, including "Dark Was the Night, Cold Was the Ground" by 1920s bluesman Blind Willie Johnson, whose stepmother blinded him at seven by throwing lye in his eyes after his father beat her for being with another man.
