(The famous Beatles rooftop concert in the movie "Let It Be" was filmed in 1969.)
ADDED: Hazy Dave emails:
BTW, the Beatles thing was filmed January 30, 1969, and the Airplane was apparently Taken Off the roof December 7, 1968 (not November as the story states), so it was "the" year before, if not "a" year before. Almost 8 weeks, anyway. :)Who knows which one was planned first?
