What were the Beatles doing on the day of JFK's assassination and how did they all react to it? John especially as his song "God" has the lyrics "I don't believe in Kennedy". Also did they ever visit the White House whilst in America or meet or send letters to Jackie Kennedy after the assassination?

Also why didn't they write a song dedicated to JFK like the Beach Boys' "Warmth of The Sun"?
