From about the 27 minute mark to just past the 32 minute mark, you will see a female streaker on the field. She doesn't get hauled off until the national anthem is over. Our current Prime Minister can be seen at around the 20 minute mark and just before the 48 minute mark.

I love the way the player introductions were done back then. Interesting to see three receivers and three running backs for the Als and each team with only three assistant coaches with one of those - Gene Gaines - being a playing assistant coach for the Als.
