Carl Sagan wrote this letter to Chuck Berry on the musician’s 60th birthday!
“When they tell you your music will live forever, you can usually be sure they’re exaggerating. But Johnny B. Goode is on the Voyager interstellar records attached to NASA’s Voyager spacecraft — now two billion miles from Earth and bound for the stars. These records will last a billion years or more.
Happy 60th birthday, with our admiration for the music you have given to this world…
Go Johnny, go.”
