Here is an exert from FF's talk about 1975:
"that`s all we can say to John Dart the religious editor of the Los Angeles Times or anybody else out there in the world who wants to know what we have published regarding this critical year,we know its a critical year,we know we are near something,but were not saying"
The audio can be found online on Youtube and other places. His tone conveys more information on the meaning than the words do...and it is obvious that the audience receieve the meaning about 1975 and were ecstatic. You can also tell the sarcasm dripping in FF's voice when he mentioned "John Dart".
