"Differential X, Differential Y" evolved into "Differential Y, Differential X". We don't do either of those anymore, but do cheerleaders actually do any kind of organized cheers anymore, other than "Yellow"....."Jacket"?GT Notre Dame 1976 - my freshman year. We beat them without completing a pass - not sure we even attempted one. I remember dancing in front of the GT cheerleaders after the game. Amazing I can remember anything after how much rum consumed - I know should have been whiskey. Speaking of the GT cheerleaders, why don't we do the differential X, differential Y cheer anymore?
