Forty-six years ago today, on April 18, 1970, Johnny Cash played at the White House for Richard Nixon. The president made a request for 'A Boy Named Sue' and of course the Man in Black played the song for Mr. Nixon.

Of course, the song was originally recorded at San Quentin prison in 1969, so it's pretty safe to assume, Cash had quite a different audience when he played the song at the White House.
