A member of Alpha Phi Alpha has made a great documentary about the history of stepping at Arkansas State University and beyond and I suggest everyone check it out. I am a member of Omega Psi Phi and we were represented pretty well in the video as well as the other GLO's. Its a three part video and quite long but it is well worth the time.

Sadly I am not in the video.
