I believe I did in 1974, but I was just coming into the org and didn't realize the significance of the part he played.
It was a Sunday at a stadium on the campus of the University of Alabama in Tuscaloosa. All the "friends" were almost beside themselves with excitement, so looking back, it must have been F. W. Franz!
I'd worked until 6 pm that Saturday night, had a one year old teething child, and had to arise at 3 am to get ready for the bus trip.
When we arrived, the weather had turned colder, the stadium was quite warm, and I fell asleep a few minutes into the talk. All I remember is a series of yips and yaps from the speaker with a lot of references to 1975.
We returned late that night, I had to get up for work that Monday morning, and I couldn't recall anything exceptional about the occasion.
I still can't.
Oh well ...
