1972 Sugar Bowl is on youtube..
Use to be a guy on AUFamily that had DVD archives dating back to the late 60's/early 70's. Bought several of them and I use to have his e-mail saved. Might ask some of the folks over there if they remember him. I'm sure one of them will.
Edit to add: Pretty sure his e-mail was bustatrojan@charter.net. Not 100% though.
