to clarify for people OP is referring to the Speech Safire wrote in case the astronauts died on the trip.

Luckily, Safire’s memo was not needed as the astronauts returned safely. Few knew of the secret contingency plan until it became public in 1999, the 30th anniversary of Apollo 11’s moon landing, after Los Angeles Times reporter Jim Mann discovered it while conducting unrelated research at the National Archives. Aldrin read the prepared eulogy and later wrote, “I am proud to say that our mission accomplished the same goals—and brought us back home safely.”

Based on what the article implies I'm assuming Buzz and Neil and Michael Collins (lets not forget the other guy on the mission) didn't read it before it got released to the public in 1999. But my sources don't seem clear on this so if anyone knows otherwise let me know.

and here is the speech:
