Oh, sorry... I thought you wanted a list of corps that are active now that didn't exist in 1972. My bad.
Corps die, corps are resurrected, new corps begin. It's the circle of life. I'm tired of this argument.
(EDIT) And that's leaving out a bunch of corps that didn't go to finals... Impulse, Incognito, etc.
