 CONT: It is said that Nicky Driscoll died on the Halloween before  the Kennedy assassination, which would be 31 October 1963. Indeed,  Angela finds a ticket stub from the dance with that year on it.  However, the yearbook she checks to find Nicky Driscolls picture is  the yearbook from the year 1963, which would have been for the year  before, for the class of 1963, who would have graduated in May/June  of that year. Instead she finds Nicky Driscolls picture with the  phrase "In Memorium" (sic), which would normally appear in the class  of 1964s yearbook, since that would come at the end of that school  year. Also, the ghost dance in the gym announces that the dance is  for the class of 63, another reference to the class that would have  already have graduated.
