The Man in Black, Johnny Cash, would have turned 80 this Sunday, February 26. To mark the anniversary, OpenAir will start every hour this weekend with a Johnny Cash song. Cash made music throughout six decades, American originals that will be part of the culture for many years to come. He sang in concert halls, on his national television show, in developing nations, on reservations, and in prisons. Johnny Cash: The 80th Anniversary celebration kicks off at 5 pm Friday and goes all weekend.
