I was 4 years old at the '69 Kansas Assembly, we were there again in '73. The best thing about 73 was that my dad had found a large stack of comic books at a garage sale just before we went on the trip, and that kept us entertained all the way there and back, and in between.
It's funny:I can remember quite a bit about those comic books (mostly Archie, Richie Rich, Sad Sack), but I can't remember much about that convention.
Oh, except for the David and Bathsheba drama. That's where at the end of the drama, a character says (and I am NOT making this up!) "This is such a happy moment, let's all sing song number such and such!" So the audience gets to sing this song, afterwards, the session conductor then sheepishly says, "Before the session close, let's all sing song number such and such." No kidding! Another song to be sung before lunch! That is the first time in my memory that we ever sang two songs back to back at a meeting of any kind....
