Dale Sievert, the one with the disheveled and unkempt dark hair (actually, the only male with any hair to speak of, and without dye, as well).
Bob Kattner, good looking--but lacking any hair since having it ripped out when he caught it in his father's meat grinder at Kattner Bros. Meat Market on Marshall Street (check out the story in the Herald-Times archives, February 6th, 1962).
Vic Schiegg, the only one not smiling because he had to pick the entire tab.
Nancy Parker, the only one in the group who graduated in the 1980s, though that was in Arizona years, so one has to adjust for the time zone change, multiplied by many years.
