Because it's never a bad time to listen to Marshall McLuhan. "Marshall McLuhan appeared on the Dick Cavett Show in December of 1970 along with Truman Capote and Chicago Bears running back, Gayle Sayers. Both Capote and Sayers participated in the discussion with McLuhan. This recording was made on reel-to-reel audio tape in 1970 and directly transferred to computer in 2005." Via Brent on FLNW.
