Here is a bit of trivia from around 1965:
I graduated from UT Austin with (rather, at the same time as) Lynda Bird Johnson, oldest daughter of Lyndon Baines and Lady Bird Johnson. I saw her in her cap and gown just before the ceremony, walking down a wide sidewalk that extends a long way down in front of the UT library. She was surrounded by secret service agents, also in caps and gowns. They were looking about suspiciously. They reminded me of a flock of blackbirds.
LBJ and Lady Bird were there in the audience, of course, and I had a good view of them. My parents were there, too; it was a relatively small summer graduation outside on the “mall.” Apparently, the Johnsons had asked that the speakers pay no particular attention to them, as nobody even introduced them.
LBJ had the world’s longest ear lobes.
I borrowed this picture of the Johnsons from this site: americanpicturelinks.com/
